"This tungsten is used to make lamps..."

Zhao Long laughed and said, "We don't have enough methods and technology, so we can only extract some tungsten from the iron ore." 81 Chinese website

“Make a light?”

“Yes, electric light.”

Zhao Long smiled and said, "When I make it, you will know."

"Oh? What's the difference between this electric light, compared to the lantern made by Mr.?"

Meng Yi asked curiously after hearing this.

"That's not the same level at all..."

Zhao Long smiled and said, "If you have the opportunity to go outside, you will know that the dick is all over the place. It's all covered with electric lights! It's not afraid of wind and sunlight, and it can be made into all kinds of things.

With the same shape, we will definitely have electric lights here in the future...but..."

As he said that, Zhao Long sighed, "What a pity, we have to find the tungsten first!"

"Sir, can you only use the tungsten you mentioned for this lamp?"

On the side, Ying Zheng couldn't help asking curiously when he saw this.

"There are air lamps, but that one is even harder..."

Zhao Long spread his hands and said helplessly, "Our village can't handle a small tungsten wire lamp. It's more than a hundred times more difficult than ours, so don't think about it..."

"But that's the case..."

After hearing this, Ying Zheng and others were a little disappointed.

"Okay, then I will find more people to help you, sir, and find it earlier?"

Ying Zheng looked at Zhao Long and said.

"This is not a question of too many people... Of course, it's better to have more people..."

Zhao Long smiled and said, "The key is that the method we use is too simple... There are still many things in our village, so let's do it one by one... Don't worry!"

"Yeah...that's fine..."

...

In a flash, more than half a month passed again...

In ancient times, looking for tungsten was really not something that humans could do.

Fortunately, Zhao Long still knows a little about this. After all, he is a person who has obtained a comprehensive science 220 degree in high school, and he also has a minor in chemistry in college.

"The emperor pays off! The second brother, this should be tungsten!"

Zhao Long was carrying a small glass tube, and a black metal bump was ecstatic.

On the other side of him, Meng Yi's face was also covered with traces left by metal.

"Sir?"

Meng Yi also said excitedly, "That's what we did?"

It’s true that even Meng Yi would be tortured crazy these days.

After all, he used to do art work, and he was really unable to do such boring and boring science dogs.

If it weren't for Ying Zheng's instructions, he would have really wanted to leave.

My dignified imperial court minister actually worked hard for half a month to find a broken metal stone?

It's simply unimaginable!

"It's almost the same..."

Zhao Long said, "The next thing is to draw the wire... If these are really tungsten, they will be made into similar metal wires, and they will shine!"

"Okay, OK! I'll inform the village chief now!"

“It’s OK…”

During these days, Ying Zheng sometimes comes to see if he has something to do or not, and he will come to see the progress.

Of course, almost every time I return disappointed.

After all, it wouldn't be difficult to find some raw materials in a real chemistry laboratory and find some for separation.

However, Zhao Long basically has nothing here!

Even those reaction reagents are the simplest to do, and they can't even make up for it.

And what should I do if the rest is really not a hard condition? I can only guess!

Zhao Long also guessed several times in a row, and this time he finally got a better grasp of it.

"Okay, I'll go now!"

Meng Yi turned his head and left, while Zhao Long put the piece of tungsten on the fire, which made people quickly pull up the bellows.

The melting point of tungsten is 4,000 degrees, while iron is only more than 1,000 degrees. This gap is huge.

This is why, in ancient times, iron could not be pure iron. Many metals were theoretically alloys.

If the higher melting point cannot be reached, the impurities inside cannot be identified at all.

Therefore, ancient weapons easily rust.

Of course, in many cases, modern times is also the same. It is not that modern technology does not meet the standards, but that it is to let you buy new products early.

Promote economic recycling...

For Zhao Long, fortunately, now that he has coal, he will improve the air blowing equipment to melt the tungsten and turn it back into silk.

Of course, it would be great to be able to reach a level of a moment.

They don’t have that kind of spray gun, they rely entirely on manual labor, so it’s naturally very difficult.

call……

Huhu...

"Sir, I heard that tungsten has been found?"

"Not sure, but it's almost..."

Zhao Long smiled and said, "If you can reach such a high melting point, it is still the appearance color, then it is definitely tungsten!"

Yes, it is actually not difficult to judge the way of metal.

First of all, look at the appearance of the metal.

This is also the most direct!

After that, by judging the temperature by the color of the flame, the temperature level and the melting point, you can distinguish many metals!

Zhao Long has no other equipment, and the reagents are the simplest, but this does not prevent him from getting things done!

"Okay, I wonder when this tungsten wire lamp can be made?"

"Hey, you old Zhao, that's a big deal..."

Zhao Long smiled and said, "Don't worry, when the filaments cool down, I will put them in the glass cover. Turn around, we will take the sewage river and try the generator!"

"well!"

After hearing this, Ying Zheng looked at the burning tungsten wire and felt a little expectant.

lamp?
