Ores And Minerals

Leading Manufacturer, Supplier & Retailer of Fused Silica Powder, Fused Silica Lumps, Fused Silica Lump and Fused Silica Grade-A.

Fused Silica Powder

We are offering 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 powder form by ball mill. 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(emc), fusion bounded epoxy(fbe).

Fused Silica Lump

₹ 31,675 / Metric Ton Get Latest Price

Min. Order (MOQ) 1 Metric Ton

SiO2 Silicon Dioxide 99.7-99.9%

Size 1-5cm, 1-10cm

We are offering fused silica lump. Chem&size minerals fused silica is produced by melting high purity natural silica sand(quartz sand) at 2000 12 hours. In the fusing process, the crystalline phase of silica sand transforms into amorphous phase. After cooling, fused silica ingot is made out with high purity amorphous silicon oxide. Fused silica ingot is separated into 5-10cm lumps grade a, grade b and grade c according to the black point size.Because fused silica has a very low thermal conductivity and excellent thermal shock resistance, fused silica is widely used in lots of fields of investment casting, refractory, technical thermal ceramic, epoxy modling compound, fusion bounded epoxy powder coating.
