Fused silica

Fused Silica is maded from the excellent fused silica sand, according to different usage, we can manufacture granular form fused silica and fine powder of different specifications by crushing, deiron, purify and classification. The special features of this product: consistent chemistry, excellent thermal shock resistance, hard wearing, low thermal expansion, high purity, low thermal conductivity, low electrical conductivity and many other characters.
