Fused Silica
Process Of Production And Characteristic
Fused silica is made of high purity crystal silica by electrically fusing (fusing temperature 1800-2000℃) 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.
Applications:
(1). Silica fume in Concrete
• Can increacing strength, density
• Frost resistance, Early strength,
• abrasion resistance performance
• anti-cavitations
(2). Silica fume in Cement
Strengthens the fibre cement product
(3) Silica fume is used in refractory
Greatly improved products strength and high temperature performance.
(4) Other Applications for Silica Fume
• Rubber industry
• Anti-caking industry
• Pellet binder
• Waterglass industry
