Two Thousand One Hundred and Fifty-Six Major Discoveries

The seawater of this generation is not too deep, only more than 300 meters.

And the ocean current is relatively stable, there is no too fast turbulence.

After the robot was put down, it only took ten minutes to go down to the bottom of the sea.

As soon as the robot landed, it stirred up a large cloud of dust on the seafloor.

This scene shocked everyone, knowing that the robot went to work under the sea.

The most feared situation is that the sea sand on the seabed is too soft.

Because of one carelessness, the robot may be trapped.

If that happens, it's going to be a big problem.

Without sufficient focus, the robot will only sink deeper and deeper, and the losses will be great at that time.

Fortunately, after the sea sand was stirred up this time, it fell down in a short time.

Before that, the miners followed the instructions and did not dare to operate the robot at all.

After a while, when the underwater sight situation improved, the miner's first job was to bow his head.

I looked at where Haisha had gone, but fortunately, it just missed the robot's feet just now.

Then the miner operated the robot and took two steps, and then he gradually felt relieved.

It turns out that the quality of the sea sand here is very light, so there is more floating sand on the seabed.

And in the places not deep below these floating sands, is the solid seabed.

But this also aroused everyone's curiosity, what is the situation, and why the sea sand here is so light.

Then, after operating the undersea sonar and some detection, it was only to find out the situation.

It turned out to be dozens of nautical miles away from here, and an active volcano on the sea floor was erupting.

And the lava spewed out by the volcano continuously vaporized and cooled directly on the seabed, which brought countless volcanic ash.

These volcanic ash drifted here along the ocean currents.

After getting the news, everyone was ecstatic.

Because these volcanic ash are good things!

Everyone knows that there are the most active volcanoes in the Pacific Ocean.

On land, Indonesia has the most volcanoes.

And many islands in Indonesia, as long as there are volcanic islands, they are all densely wooded, and there is no big island with water, grass and wind.

For example, the four main islands of Indonesia, among which Kalimantan and Sulaweswi, have the most fertile land and are most suitable for agriculture.

While the other two large islands, such as Java, and Medan, the situation is more general.

Although there are dense tropical rain forests, the land on those two islands is relatively barren. If crops are grown, even if they can grow, the quality and yield are very average.

And the reason for this is because there are many active volcanoes on Kalimantan and Sulawesh.

It often erupts, and at the same time, although a large amount of volcanic rock will be ejected, a large amount of volcanic ash will also be ejected.

And when these volcanic ash falls on the island, it will become fertile soil, supplementing the fertility of the land.

Make the land here more suitable for the growth of crops.

In Medan and Java, although there are some volcanoes, the eruption is not as frequent as the other two islands.

The most important thing is that the spewed volcanic ash will be washed away by the dense rain and washed into the sea not long after it falls.

Therefore, the land here is red soil similar to the soil structure of several provinces in southern my country, such as Guangdong and Guangxi.

The acidity is high, but the fertility of the soil is insufficient, and the yield and quality of crops are not good.

This is just volcanic ash on land, and the volcanic ash ejected by underwater volcanoes is even more incredible.

Because it will be ejected with a lot of minerals, and once it comes out, it will be quickly cooled by the seawater.

Some minerals in the valley will also react with various substances in the seawater, so other substances will be formed.

Among them are rare earths, and especially high-grade rare earths that contain very expensive metal elements.

Only then did everyone understand the purpose of the exploration ship for everyone to come here.

Obviously this should be the only way for the ocean currents after the eruption, and those ocean currents will sweep the volcanic ash and wash it here.

Everyone here, don't need too much mining, just pick up ready-made ones here.

After a while, the robot was hoisted up.

And the robot also carries a sample bag with all kinds of sea sand collected from under the water.

Chen Cheng and the others were immediately called to clean and maintain the robot.

The samples in the sample bag were quickly sent to the laboratory on the ship.

After waiting for about an hour, it was time for dinner.

Finally the good news came out, and today they hit a treasure.

The rare earths here are indeed very high-grade rare earths.

Because it contains a lot of scandium, indium and palladium, and other rare metals.

Now everyone is prosperous...

As soon as the news came out, Mr. Zhou from Harbin Institute of Technology was excited, and even Mr. Wang, who brought Harbin Engineering, was rarely happy.

The two teachers even drank a lot during dinner.

He kept murmuring, and this time he finally found a large amount of valuable minerals for the country.

As for Chen Cheng, although he was happy, he didn't know what these mines could be used for.

Fortunately, he has a mobile phone here, so he can save his mother.

This investigation is incredible. It turns out that these metals are used so much.

Just like the metal indium, that thing is a special alloy material that can be used to make aero-engine blades.

In this regard, we have only made major breakthroughs in recent years.

However, we are taking the old way, using titanium alloy materials and learning from Mao bears.

On the other hand, the Americans have already used ultra-high nano-molecule materials.

So other people's aviation can achieve 30,000 hours of life, and super stable characteristics.

On our side, 3,000 hours is a big deal.

Although the emergence of Spark Technology is to help our aircraft manufacturers to solve the problem of finishing.

But for the material, Xinghuo Technology didn't dare to make a move.

In this regard, we also need to test the efforts of our country's scientists.

And we have just conquered the technology of rhenium alloy. As for this indium alloy, we have only heard about it, but we have not tested it.

Why, because indium is really too little, and the price is very expensive.

The main production areas are usually concentrated in North and South America, and the control of this rare metal is very strict in the old United States.

Even if we want to buy some back, we can't buy it.

And now, we don't have to buy it anymore. With these rare earths, we can finally manage enough.

Chen Cheng and the others may not know the value of this humble metal.

But the two teachers from Harbin Institute of Technology and Harbin Engineering know too much about the magic of this metal.
