High pure Graphite block

High pure graphite block is the main products of industrial production. And when we manufacture high pure graphite metal, semiconductor material, rare metal we need many high pure graphite as parts. The characteristic of high pure graphite is able to endure high temperature, acid and alkali,etc. At the same time there is almost no impurity in high pure graphite.

It is almost the same manufacturing techniques between high pure graphite and common graphite, but the high pure graphite has some special characteristics.

You need to choose the material which has very low ash content. Such as when you choose petroleum coke as material. The ash of petroleum coke should be under 0.15%. Generally speaking, the high pure graphite block manufacture by die stamping. And also we can manufacture it by isostatic pressing technology. How to get the high pure graphite block the key point is to high temperature graphitization. And the temperature has to be upper the temperature manufacturing the common graphite electrode. You'd better add some halogen group elements to get more higher pure graphite block. You can get any shape of the graphite products because of wonderful processability. You can use lathe, milling machine , drill press machine and so on to manufacture any kind of figure. And we also can use file and abrasive paper to fix the cutter mark or refined processing of streamline parts. The efficiency is very high when we use the high pure graphite material to have electric spoarkmachining.
