Diamond is the hardest mineral, so some people call it "the king of hardness". Cutting glass must rely on it, and grinding high-grade materials mostly depends on it. In addition, it is an advanced material for heat dissipation, not to mention decoration and wearing. You know, its price is also high carat (equal to 0.2 grams) diamonds equal to two tons of rice! This has far surpassed gold.
What about graphite? It is one of the softest minerals. It doesn't have many seats except some pencils, so it can be used as insulation material. As an ornament Wishful thinking! The price is also very cheap, and diamonds are thousands of times more expensive than it.
Looking closely, I suddenly found that there is such a big gap between them-one is expensive and the other is cheap; One hardness 10, one hardness 1: one is transparent and pure, and the other is extremely dirty; One is very useful and the other is almost useless. What a big difference this is! What two extremes! However, their ingredients are all carbon!
Stranger still, they were treated in the opposite way when they were formed. This is thought-provoking.
Let's take a look at their formation process! A piece of carbon is buried deep underground, close to the center of the earth, and it has to endure the destruction of high temperature and high pressure every day, but it has been patient and patient.
Graphite is another kind of carbon. It lives a carefree life every day and never wants to be tested in the past.
Finally, the first piece of carbon stood the test. This piece of carbon, no, should be called a diamond now. This diamond suddenly appreciated and became an enviable "bridge".
