Refractory Material

Fused Silica

   Using the highest purity silica sand manufactured by our plant, we manufacture it by electrically fusing(fusing temperature 1720-2300 ≧ )to amorphous Silicon dioxide, then specially engineered ingots, granular and flour form designed for different usage. The appearance of this product is colourless and transplanted; a bit of them will transplant frog shape. 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 excellencies.

   Size Available:
   (ingot, granules and powder) 5-100mm, 3-50mm, 8-5mm, 5-3mm, 3-1mm, 1mm-0, in accordance with customer¨s request
