Product Introduction

Graphite crucible is a kind of container made of high temperature refractory material, which is widely used in various high temperature experiments and industrial production processes. It has the advantages of good thermal conductivity, good chemical stability, high temperature corrosion resistance, and can withstand physical and chemical reactions at high temperatures, and is an indispensable and important equipment in high temperature experiments and industrial production.

The main raw materials of graphite crucible are high purity natural graphite, artificial graphite, ceramics, etc., refined through dozens of processes, with uniform structure, high density, high strength characteristics. Its surface is smooth, not easy to adhere to impurities, for high temperature material reaction has a good isolation effect, but also has excellent thermal conductivity, can quickly transfer and disperse heat.
