Product Introduction

Fused Silica is made of high purity quartz sand by electrically fused in electric arc furnaces, then the crystalline quartz sand transformed into amorphous silicon dioxide.

Features

1.Low thermal conductivity.

2.Low thermal expansion.

3.Small heat capacity.

Application

Mainly used for manufacturing glass, refractory materials, smelting ferrosilicon, coatings, rubber fillers, metallurgical flux, ceramics, abrasive materials, and also for metal surface treatment. In construction, it can be used to make acid-resistant concrete and acid-resistant mortar because of its strong resistance to acid media.
