The high purity graphite products are widely used in metallurgy, machinery, electronics, chemical, electrical, food and other industrial fields. For emitting an electron tube, thyratron, mercury arc rectifier with graphite plate,the grid plate; semiconductor technology with graphite boat dish, the crucible, heating element, single crystal furnace heater, metal gasification with graphite ware, continuous casting mold, pressure sintering graphite template, electric spark machining of the graphite electrode. Faced with so many applications,Just only one way to prepare high purity graphite is clearly not enough, the following are the high purity graphite preparation methods which given by we , the graphite products manufacturer : 1).The theory of high temperature process for the preparation of high purity graphite: we can utilize the low…
The mechanical graphite products which made of the wear-resistant carbon and graphite products are often used in the machinery industry and in the chemical production as a structural material extensively , it has become an important branch of carbon and graphite products industry, regardless of in the domestic or foreign, the variety and quantity of the wear-resistant carbon and the graphite products are in rapid development. The mechanical graphite products materials compared with many metal or non-metallic materials, it has the high thermal stability, the higher thermal conductivity, the low thermal expansion coefficient , especially the carbon and graphite materials have no chemical reaction with the majority of acid, alkali and salt solution. The graphite material has the self lubrication…
1).The High Purity Graphite The high purity graphite generally refers to the amount of carbon containing more than 99.99% of graphite and in the organizational structure it can be divided into three categories: coarse grain structure, fine grain structure and ultra-fine grain structure. The basic material of the integrated circuit is mainly silicon single crystal chip, at present silicon single crystal growth process is mainly uses in Czochralski (CZ), Czochralski silicon accounted for about 80% of the total amount of silicon in the global electronics industry, the graphite piece in Czochralski silicon furnace is a consumable,we use the high purity graphite material to process the Czochralski silicon furnace heating system. Another important use of high purity graphite is process various…
