Graphite blocks are delaminated due to oxidation at high temperatures and appear black. 1 degree of graphite block, the stratification is very obvious, and black luster can be seen. The graphite block at 80 degrees has been completely delaminated, but the luminescence produced by the temperature can still be seen. The 90-degree graphite block, that is, low-temperature graphite, will also produce stratification, but it seems very obvious. At high temperature, graphite has fluidity, the thickness gradually decreases, and the stratification will become more and more obvious. The 95-degree graphite block will have a layered phenomenon, which is white. Graphite blocks with a temperature of 35 degrees must be polished with wax, and the stratification can be seen.

already. Graphene, can it be typed with a mobile phone so-so?

Graphene is not very stable. The amount of graphite in a metal mine is calculated in tens of billions, and there are almost no tens of billions of orders. The reserves of more than ten billion cannot meet the needs of use. The solid phase of graphene is carbon atoms + lattice electrons (the oxygen atoms have local electrons, and the electron eccentricity is too large). Oxygen atoms are very unstable, and are prone to interlayer transformation. Over the years, sulfides will be formed and metals will be vaporized. At present, the processing of graphene is already a mature process. Basically, silicon precision processing can be used, and graphite made of silicon dioxide can also be used (high-altitude grinding process), but this type of precision processing is relatively expensive.

my country's scientific research has not caught up with developed countries. At present, developed countries have begun to use tefc instead of nor packaging. They are the first to use mir packaging in eco3 graphene, so that gfb (graphene two-dimensional structure network) can easily become a two-dimensional copper plate, which is the world's leading edge The contribution of technology is still indispensable.
