Graphite Crucible By Qingdao Rares Technology Co.,ltd.

We are engaged in manufacturing and exporting excellent quality Graphite Crucible to our valuable clients. Graphite crucible can withstand the high temperature, and has good resistance to chemical erosion and thermal shock. Especially graphite crucible is ideal for the melting of aluminum, copper and other metals.
Quartz crucible has the advantages of high purity ,high temperature resistance, with big size ,good thermal insulation, economization on energy, quality stability etc.

Fused quartz crucibles are used in the manufacture of silicon metal for semiconductor wafer applications and polysilicon. In order to produce high quality wafers, starting materials are added to a crucible heated to high temperatures and pulled from the melt as a single crystal. Fused Quartz is one of the few materials that can combine the high purity and high temperature properties required for this process.
We can offers graphite crucibles & Ceramics (Quartz) crucibles in different sizes and types.
