In fact, Zhang Hao had a little guess about Xuan Tie:

isotope!

Black iron and iron exist in the form of iron oxide in ore. Therefore, in the process of ore screening, it is impossible to distinguish between black iron and iron.

During the smelting process, charcoal is needed for reduction. In the environment without aura, it can be oxidized into rust, which is difficult to separate from each other.

In addition, the magnetic properties and some chemical properties are exactly the same.

What is commendable is that the best black iron purified by the Zhang family, which is 99.9% of the black iron density, is just about one fiftieth of the rough iron!

All this seems to point to the isotope of iron: iron 57!

Of course, the molecular weight of 57 is based on the standards of another world; anyway, Zhang Hao remembers saying in the textbook, usually the molecular weight of iron is 56, and there are other isotopes of iron 54 and iron 57 in nature.

The "Xuan Tie" here is just a bit heavier, most likely it is Tie 57.

Iron 57 has one more neutron than Iron 56!

In other worlds, it is said that ‘neutron’ has no attributes; most scientific research is also conducted around electrons and protons.

Perhaps, neutrons are not without attributes. It is just that there is no aura in another world and neutrons are superfluous. And with the aura in this world, the importance of neutrons is revealed!

Zhang Hao returned to his room, took out a notebook, and began to write and draw pictures:

If this conjecture is correct, then Zhang Hao has a little speculation about the nature and function of different fires and real fires-inspire Reiki and let neutrons capture Reiki!

To verify this idea, it is relatively simple in principle. According to ordinary observation, if you want to ‘excite Reiki’, the ordinary flame temperature is far from enough, so what kind of fire or real fire is needed.

And the easiest way to get high temperature is ‘high pressure’. The representative product is: pressure cooker.

Of course, if you want to get a temperature far beyond the general flame, this pressure is only afraid of being extraordinary.

According to the usual smelting data, this temperature must exceed or even far exceed two thousand degrees. And more than two thousand degrees is enough to melt the black iron.

Well, this requires looking for tungsten ore or graphite. But in terms of Zhang's weak technology, graphite is the first choice.

No... wait, this is the practice world, there is a formation! I don't know if the formation method can be used to meet the requirements?

After lunch, Zhang Hao found his father and asked questions about formation.

"An airtight, can withstand high temperature, high pressure, and large enough area?" Zhang Shengde said after thinking for a while. "Some of these formations, the formation of the seal ground fire in our smelting base should be .

That method is called... Yes, it is called Sleepy Dragon Array, yes, it is called Sleepy Dragon Array. "

"Dad, you can't call your own name?"

"Mixed boy!" Zhang Shengde slapped Zhang Hao's head, but didn't use his strength. "That formation was helped by others. How can I remember clearly. By the way, that formation was still arranged by your uncle."

"What about my uncle?" Zhang Hao was curious. He had never seen anyone on his mother's side. It seemed to evaporate out of thin air. Isn't there any dog ​​blood plot?

Zhang Shengde's face is a little weird: "Your uncle...can't judge it. I finally saw him, more than twenty years ago. He is a master of formation, and his cultivation base has reached the peak of the Jindan period.

But he likes to travel around the world, saying that he wants to find an opportunity to break through the infancy. After leaving your mother, after setting up the formation, she drifted away.

There is no more audio so far. "

Zhang Hao immediately frowned, feeling...an unreliable guy again!

"Your mother has been crying several times over the years. But the world is vast, where to find it. Hey..."

"What about my grandma and grandpa?"

"When I met your mother, only your mother and your uncle. At that time your mother was just 16 years old."

…………

In the afternoon, Zhang Hao came to the meeting room of the Refining Association.

Zhou Jue warmly greeted Zhang Hao, "Brother, sit here."

Zhou Jue asked Zhang Hao to sit as the vice chairman. Originally the vice chairman was Zhang Shengye, but Zhang Shengye is now very injured and his mentality is not very good, so... absent.

Zhang Hao greeted everyone. Compared with the Xuantie Guild, the atmosphere of the Refining Guild was more harmonious.

No, Zhang Hao hasn't sat down yet, Mei Qianyun chuckled lightly: "Zhang Hao, Zhou Jue said just now that you have the habit of sleeping lazy?"

A good laugh broke out all around.

Zhang Hao sat black and gray, but saw Zhou Jue in front of him put a child's fist-sized irregular silver-white metal, the metal was a little yellow-white, and the surface had a spiritual disc spinning, and the aura was slightly deep. .

"This is... star gold?"

Zhou Jue nodded: "The Ouchi guard sent, more than 25 kg. This thing has almost three times more weight than the black iron."

"Can I see it?"

Zhou Jue nodded. Zhang Hao took it and tried it. By the way, he made an appraisal with his not yet mature appraisal technique. The child's fist-sized metal weighed 25 kg, and the density was roughly 3.5 times that of the black iron.

Zhang Hao's eyes narrowed: the metal from space, almost 3.5 times denser than iron, exists as a single substance. Wouldn't this be...Iridium?

And remember that on the periodic table, iridium seems to have a molecular weight of 192 and an atomic number of 77. That is to say, iridium has 115 neutrons, far more than protons!

If this thing is really iridium, then Zhang Hao can conclude: Reiki and neutron must be related.

Zhang Hao quietly put down the Jingjin Jingjin, and by the way gave him praise.

After a few more people came, Zhou Jue clapped his hands: "The meeting began. Today we will discuss the management model, determine the various departments and responsible persons, and a new production method."

The meeting continued until the evening, especially when it came to new production methods, and involved issues such as division of labor and streamlining operations. Zhang Hao showed a little more.

At the end of the meeting, Zhang Hao suddenly stood up. "Wait a minute, I want to buy a set of flags or arrays for the trapped dragon array. It needs to be able to withstand the high temperature, high pressure, and the kind of airtight."

Mei Qianyun first said: "What do you want is a formation that can withstand high temperature, high pressure and airtightness?"

"Correct."

"We have a set of ‘Bound Mountain Arrays’ in Yuxue Mountain Villa. The complete Bound Mountain Arrays can even seal volcanoes.’

Zhang Hao was overjoyed: "Come on! A simple one is fine."

Mei Qianyun immediately smiled: "A simple set of mountain binding arrays, want... a ton of black iron for alchemy!"

Zhang Hao's face suddenly became black: "Mei Xianzi, we are all acquaintances, give us a real price. You report the spirit stone, I will convert it to your black iron."

Mei Qianyun smiled triumphantly: "Zhang Hao, do you know how complicated a set of bound mountain arrays are? Even simple ones, there are 108 flags. It is enough to make the Zhang family unable to drain, trapping Yuan infantile period!"

Zhang Hao's eyes lit up: Ha, do you think about this? Okay, Zhang Hao agreed in one fell swoop and asked for the instruction manual-a jade slip.

"Tomorrow, the flag will be delivered. The Zhang family will have to prepare the black iron."

"Xuan Tie takes a little time. How about ten days?"

"it is good!"

As soon as Mei Qianyun finished speaking, Mu Yingying rushed to say: "We have a complete array of trapped dragons in our house, which works very well. Just a thousand high-grade spirit stones is enough."

"I want two sets! We pay with the black iron for alchemy." Zhang Hao said with a big voice.

"Okay!" Mu Mingchen received the call.

Zhou Jue finally had a chance: "Sister, our Jiuyang Sect has a more powerful "Sleepy Immortal Array", similar to the Sleepy Dragon Array, but several times more powerful."

"Then one more set! Also pay with mystic iron for alchemy."

Zhou Jue politely said: "I want a ton."

"Yes." Zhang Hao is very simple, "But the price is higher?"

"Brother assured, if we find that the price is expensive in the future, we will refund it in full!"

Zhang Hao smiled and turned his head to look at everyone: "Who has a similar formation, welcome to provide it. All Zhang family pays for the Alchemy Iron. The cost price is paid, only once!"

"Master Zhang, we have a set of "Zhoutian Fengmo Formation"."

"We have the'Great Zhoutian Sealing Demon Array' and the'Eight Fang Demon Array'."

"We have the'Legendary Array'!"

"We have……"
