Description Vitreous Silica is the glassing modification of silcon dioxide with a purity of 99.9% in the transparent form and is called fused silica. All our silica ware products are made out of fused silica. Fused silica is completely unaffected by acids such as sulpuric, nitric and hydrochloric, however, it can be affected by hdrofluric acid and at high temperatures also by phosphoric acid. Hot alkalies and certain metallic oxides also react on fused silica. Fused silica is boron free They are of very low expansion and hence have excellent dimensional stability and thermal shock resistance Technical Specifications: - Electrical resistivity - (at 350°C) 7 x 107 ohm cm - Average co-efficient of expansion - 5.5 x 10-7 / °C - Softening point - 1685° C - Annealing point - 1200° C - Operating temperature (continuous) - 1050° C - Operating temperature (intermittent) - 1350° C Working temperature - 1950° C Strain point - 1120° C
