Fused Silica

Product Number: SC-FS
The fused silica supplied by Chuo Cheng is a colorless and transparent solid with the size of 40-10 mesh or 60-20 mesh, made from high-quality vein quartz. This refractory raw material is mainly suitable for solar crucible for polycrystalline silicon ingot, electronics, semi-conductor, quartz ceramic roll, etc. In terms of precision casting, the fused silica can replace zircon sand and zircon powder to lower cost up to 50%.It is a high-end refractory material as well as an ideal filling material for chemical industry (like oil paint).
