Raw material and manufacturing process of graphite electrode
Graphite electrode is a high temperature resistant graphite conductive material produced by petroleum knead, needle coke as aggregate an...
Because of its good physical properties, reaction-sintered silicon carbide has been widely used as a major chemical raw material. Its scope of application has three aspects: for the production of a...
Graphite electrode is mainly made of petroleum coke and needle coke as raw materials and coal asphalt as binder through calcination, batching, kneading, molding, roasting, graphitization and machin...
Sintered silicon carbide is an important ceramic material, which is widely used in high temperature, high pressure and high strength fields. Reaction sintering of sic is a key step in preparing sin...
After the wafer has gone through the previous process, the chip preparation is completed, and it needs to be cut to separate the chips on the wafer, and finally packaged. The wafer cutting process ...
As the carrier of normal silicon wafers in the production of coating process, the graphite boat has many boat wafers with a certain interval in the structure, and there is a very narrow space betwe...
