On Earth, the price of single-layer graphene is very expensive, in the final analysis, because the earth technology has not developed to the extent that it can mass-produce single-layer graphene.

But in the ruins, single-layer graphene is a technology that has long been popularized, and before the disaster broke out, graphene can be seen everywhere in the electronic products and furniture products used by Sophia and others.

For example, graphene batteries, graphene screens, graphite thermal conductive films, and even the clothes worn by Sophia are also added with double-layer graphene materials that increase toughness and strength, resulting in the penetration resistance of this dress is stronger than that of steel plates.

......

Hearing Sophia's request to trade gold, Jiang Bo's heart became even more uncomfortable.

But his face could only remain silent, and he said lightly: "Gold...... I don't need it now, ...... later. Perhaps. ”

"Is that so...... a look of disappointment flashed across Sophia's pretty face, and she had worked hard to collect more than five hundred tons of gold, but no one needed it now.

Jiang Bo: "However, you don't have to worry, I can still give you the ratio of graphene to food in a ratio of 1:1."

Of course, remember, I want a single layer of complete graphene, not mesoporous nor multilayered. ”

Sophia's eyes lit up slightly when she heard this, and at the same time she breathed a sigh of relief, and said happily: "Thank you for your generosity, I understand, then you wait for my news, I will find you graphene as soon as possible, well, single-layer graphene!"

"Good. But remember, you only have a week. ”

"Got it. ”

......

When he woke up the next day, just after breakfast, Jiang Bo was about to call Zhuang Miao, but the latter called first.

"Boss, the industrial situation of Xingyue Company, I have basically investigated it here, do you want careful information, or do you ......?"

"Let's talk about the purchase price directly. Jiang Bo said simply.

"The valuation of assets and brands is about 12.5 billion, if you want to buy all shares, according to the experience of the previous acquisitions, I think if we use cash to acquire, the premium will not be too large, at most 13 billion can be taken. Zhuang Miao replied.

The charm of cash is still relatively large, many people open companies just to make money, and many people find themselves trapped after entering this field.

Although the assets are huge, the money cannot be withdrawn.

Therefore, in most cases, some company CEOs are not particularly optimistic about their own industry, and when they encounter the situation of cash acquisition, there is basically a high probability that they will choose to trade with money.

It's human nature to love cash.

Jiang Bo nodded slightly: "Okay, I know." However, since Xingyue Company has investigated clearly, let's put it aside for the time being, I have more important things to do for you here. ”

You say. ”

"You go back to Yangcheng now, according to the specifications last time, buy a batch of food and put it in the warehouse on the outskirts for refrigeration, I can use it." ”

"Okay, how many tons do you need?"

"I'll transfer 100 million to you, and you can just watch the money end. Jiang Bo pondered.

He didn't know how many tons of graphene Sophia could collect, but he thought that he had already made a second deal with her, and he didn't have a chance to do it a third time.

If gold is included in the option for the third trade, it will require a lot of food.

Now, you can take precautions, buy some food and store it, anyway, it won't be bad if it's refrigerated, at most it tastes a little worse, but it can still provide the energy needed by the human body, make people fill their stomachs, and it won't pit her.

After operating from his mobile phone and transferring 100 million to Zhuang Miao, he called Ma Jingping again and asked him to check the current price of graphene.

In the afternoon, Ma Jingping called Jiang Bo back and said directly: "Boss, I checked it specifically and found that there are many types of graphene, from 0.1 inches to 4 inches, and then it is divided into specific surface area of each layer, as well as single-layer, double-layer and few-layer.

I don't know, what exactly are you referring to?"

Jiang Bodao: "Single-layer graphene, with a specific surface area of 2630 square meters/g, is the largest one." ”

In fact, Jiang Bo didn't know what type of graphene Sophia could get, but it must be a single layer, but the size and specific surface area could not be determined.

After more than ten seconds, Ma Jingping replied: "The type of graphene you mentioned is made of copper-nickel alloy single crystal thin film substrate, and the domestic quotation is 3,500 yuan per gram......."

Jiang Bo was surprised: "How much? 350 yuan per gram?"

Ma Jingping replied: "It's not 350, it's 3,500 yuan per gram, in RMB." ”

"So expensive?" Jiang Bo swallowed.

Ma Jingping: "There is a reason why it is expensive, according to what I found, this kind of 4-inch single-layer graphene single-crystal wafer, at present, only the equipment of a company cooperating with the Institute of Graphene of the Chinese Academy of Sciences has the ability to prepare, and the equipment uses copper-nickel alloy single crystal thin film substrate plus epitaxial growth method.

The cost of a piece of equipment is about 200,000, and the annual output is up to 10,000 pieces......

Annual output...... About 3 grams. ”

Jiang Bo's face trembled when he heard this, well, it does make sense that it is expensive, after all...... Only 3 grams are produced a year, and people are not allowed to sell them at a high price?

This situation is normal, gram-level transactions, let alone thousands, even tens of thousands are possible.

But if it goes up to the kilogram level, just like fullerene, the price will definitely be depressed, and when it reaches the ton level, because the number is too large, it will be even more frighteningly low, and whether it can maintain 350 grams per gram is still a question.

After all, milligram and gram graphene are basically used for experiments, because the quantity is small, and the cost does not matter.

But when it comes to the ton level, it is industrial and commercial, and specific cost issues must be considered.

Jiang Bo asked again: "What about the international quotation of graphene?"

Ma Jingping said: "The price of single-layer graphene with a specific surface area of about 2,600 square meters/g ranges from 240 yuan per gram to 1,200 yuan per gram according to the size, but they are all small-scale transactions, and the single transaction volume does not exceed 10 million yuan.

A single transaction of more than 100 million yuan is basically a transaction of graphene powder.

In addition, the global graphene market size last year was about 5.5 billion RMB. ”

"The world is only 5.5 billion RMB, is it so little?" Jiang Bo frowned.

"That's right, on the one hand, the price is too expensive, on the other hand, the output is too small, most of the graphene companies are hanging sheep's head to sell dog meat, just graphene powder materials, not authentic graphene films, even if some are films, they are only graphene oxide films, and the value is low. ”

In fact, the scale of the graphene industry invested and built worldwide has exceeded 100 billion yuan.

However, ninety percent of the enterprises are in a state of loss, the heat of graphene concept stocks has long passed, the scale of the industry is large, but the production is some garbage, can not be on the table, can not be sold.

So much so that the market size has become very small.

"You should check which companies are doing research on graphene products and need a large amount of graphene, and tell me if you find it. Jiang Bo said.

"Good. ”
