"Brother Xiaoma, now that there is electricity, when will the mobile phone be made?" Lin Zhi looked at Ma Qiang with blank eyes, she was still waiting to talk to Lin Huan at any time in the future.

"This electricity doesn't work, you can't always take a power station and run all over the ground." Ma Qiang shook his head and said, "What we need is batteries, and we make generators to prepare for batteries." ”

Ma Qiang then took out the blackboard and began to draw, and Yan Fa and the others below hurriedly picked up the paper and took notes.

"The battery is divided into a battery and a dry battery, as the name suggests, the battery is a battery that can store electrical energy, this kind of battery can be used repeatedly, and then charged when it is used up, the dry battery is disposable, and it will be gone when it is used up..."

Ma Qiang actually has doubts about what to do the battery, in terms of efficiency, it is more cost-effective to make a battery than a dry battery, after all, now there are generators, and the battery can be used repeatedly, but the dry battery is simpler than the battery, such as zinc-manganese battery, as long as the material tube is enough, basically you can make this dry battery as long as you can pack the bun.

After considering the materials at hand, Ma Qiang decided to do some dry batteries to practice his hands first, after all, batteries need to use things like sulfuric acid, such dangerous things, and it is not easy to install without glass containers.

It's not that other appliances can't be installed, it's just that other appliances can't see the specific situation inside, and it's easy to have problems.

After talking about the theory, Ma Qiang asked a few more questions, and after making sure that everyone had a basic understanding, he was ready to take everyone to Yue Liang's treasure house to find materials.

The blacksmiths of this era did not understand the formation of steel, but they knew how to sum up experience, and according to their experience, if they added something strange to the iron, sometimes there would be unexpected gains.

There are more ferocious ones with human blood, but there are also all kinds of beautiful stones that are picked up, and these beautiful stones are actually often monomeric ores of some metals, so the formation of some divine weapons will have the legend of adding dragon scales and phoenix feathers.

Yue Liang also has the habit of picking up or buying interesting stones when he sees them, and adding some to try the effect when the iron is rich, but until now, Yue Liang has not come across a good stone that can turn Fan Tie into a divine weapon.

Yue Liang heard that Ma Qiang was looking for materials to make treasures that could store electricity, and immediately donated all his family resources, not only him, but other blacksmiths also donated their treasures, expecting that their treasures could become part of the immortal weapons through Ma Qiang's hands.

In the future, there will be capital to blow for a lifetime.

If I hadn't picked up a divine stone in such and such a place back then, Mr. Ma's immortal artifact wouldn't have been able to make it.

Ma Qiang was accustomed to the misunderstanding of these people, and began to find the stone with peace of mind.

Ma Qiang is actually not very proficient in mineral materials, most of the materials he saw in the laboratory have been purified, and this kind of wild ore has only been seen in some ore museums.

Suddenly, a black stone attracted him.

This black stone is beautiful, with a quartz-like pattern on it, sparkling in the sunlight like a gemstone.

"This is..."Ma Qiang picked up the stone, scratched it with the dagger in his hand, and found that his dagger could not be carved.

"This stone is beautiful, isn't it? This thing is extremely hard, it was transported from Yangzhou by a merchant some time ago, I originally wanted to melt it into iron, but unfortunately it didn't melt. ”

"It's... Is this wolframite? ”

Ma Qiang felt that he was really lucky to be able to find wolframite in a place like Youzhou.

Although it may be such a piece, it is also tungsten, which is the most powerful metal in the world, and it is a treasure given to China by God.

China's tungsten ore reserves are not only the world's first, but also occupy more than half of the reserves discovered in later generations, and even because China is rich in tungsten ore, it has affected some of China's historical processes and scientific and technological development directions, for example, China's armor-piercing bullets in later generations are tungsten alloys, while the United States is depleted uranium bullets.

"Ma Lang, do you know this?" Yue Liang didn't expect Ma Qiang to know this thing, and called him Wu... Is it because the stone is dark enough?

"Yes, I know him, if I am not misjudged, this is wolframite, and it is a very good taste wolframite, tungsten is the most powerful metal in the world, it is not only extremely hard, but also extremely stable... That is, the metal made of this thing is not easy to rust. ”

"Oh? So, it's a piece of treasure? Yue Liang admired his vision a little, but fortunately bought this thing.

"Yes, there are a lot of this thing in some places in Yangzhou, but it should be extremely rare in the north, it can be said to be a priceless treasure, let's put it this way, as long as the right thing is added to the iron, then the forged tungsten steel, then it makes no difference to chop my dagger and cut wood."

Ma Qiang said, and tested this wolframite with a dagger, such hardness, it should be right.

"That's good! That's good! Then we'll melt him now! Yue Liang said that he was about to beckon someone to open the furnace.

"No, we can't melt it." Ma Qiang sighed and said, "I told my uncle before that the temperature of boiling water is 100 degrees, the temperature of the bonfire is 700 degrees, and the furnace of our iron can be heated to more than 1,600 degrees through the blower, but this tungsten, to melt it, the temperature of the furnace must be as high as 3,400 degrees, which can be said to be the most difficult metal in the world." ”

"Three... Three thousand four hundred?? "All the craftsmen were stunned by the figure.

In the early stage, in order to let the craftsmen understand the influence of temperature on forging and firing kilns, Ma Qiang has popularized the concept of temperature, although it is impossible to imagine how high the temperature of 3,400 degrees is, but when you think of boiling water is only 100 degrees, molten iron is only 1,500 degrees, and it is said that the boiling of molten iron is only 2,700 degrees, you can imagine how terrifying the temperature of 3,400 degrees is.

Even Yue Liang and the others couldn't imagine what kind of thing could withstand such a high temperature without melting.

Thinking of this, Yan Fa asked, "Sir, since this thing is the metal with the highest melting point in the world, even if it can be melted, where can you find it to hold it?" And since Mr. knows about this thing, it must be that Mr.'s master has melted it, right? ”

Ma Qiang glanced at him approvingly and said, "That's true, if this thing is melted, then there is no thing in the world that can catch him without melting, so if you want to use him, you can't melt it in the way of ironmaking, but you have to use powder metallurgy technology, we can't do this technology, let's put it aside, and when the conditions are ripe in the future, we will use him to make something fun." ”

Tungsten... The tungsten ore of later generations should be extracted into tungsten powder after a series of chemical reactions, and then tungsten powder should be used to make the required metal.

Or electric heating is also an option... But Ma Qiang does not have this demand now, such high-quality tungsten ore must be used in the most important place.

Let's put it there for now...
