1.Used for processing graphite crucible, graphite boat dish, graphite mold, graphite rotor, graphite heat generator, graphite spout, etc..
2.It is used as structural material for high temperature furnace body.
3.It is used in strong acid, strong alkali and strong corrosive environment, such as rare earth smelting and chemical industry, and processed into various parts as required.
4.Graphite rod is often used as the electric heater of high-temperature vacuum furnace. The service temperature can reach 3000 ℃. It is easy to oxidize at high temperature. Except for vacuum, it can only be used in neutral atmosphere or reducing atmosphere. Its thermal expansion coefficient is small, its thermal conductivity is large, and its resistance coefficient is (8 ~ 13) × 10-6 Ω· m, better processability than SiC and MoSi2 rods, high temperature resistance, extreme cold and extreme heat resistance, and cheaper price.
