Fused silica Introduction
 Fused silica is made of high purity crystal silica by electrically fusing (fusing temperature 1800-2000â??) to amorphous Silicon dioxide , then it was classed to different grades by manual and then specially engineered to granular and powder form. Because fused silica has a very low thermal conductivity and excellent thermal shock resistance, it is used in lots of fields of investment casting,refractory,ceramic,epoxy modling compound,fusion bounded epoxy.

Silica Sand Introduction
Quartz sand is quartz stone processed by the crushing of quartz particles. Quartz stone is a non-metallic mineral, a hard, wearable, chemical properties and stability of silicate minerals, the main mineral composition is SiO2. Quartz sand is an important industrial mineral raw materials, non-chemical dangerous goods, widely used in glass, casting, ceramics and fireproof materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical, plastics, rubber, abrasive, filter and other industries.
