ISO-Molded GraphiteBlocks

Fine-grain cold ISO-Molded graphite material is a new type of material, which was developed in the past half century. It is ofadvantageousfeatures compared to other ordinary material, like good conductive and thermal performance, high temperature resistance, corrosion resistance, high strength at high temperature, high bulk density, high purity, easily machining and so on. Since this material has so many good features, it is widely applied in lots of industries, such as manufacturing monocrystalline silicon, polycrystalline silicon and silicon ingots, EDM machining, metal continuous casting, vacuum oven, high temperature corrosion resistance container and other special applications.

Technical properties:

* After our purification treatments,the ash content will be 30-50ppm and 5ppm max.
