Overview
Silica Lid - Low Form - RIVIERA/25ml -"THERMAL PROPERTIES - THERMAL EXPANSION : Mean value of the coefficient of thermal expansion between 0 and 800ºC - 5.5 X 10-7/ºC. Fused silica is neutral to abrupt temperature changes. Vitreous silica is highly viscous. Viscosity drops uniformly as the temperature rises over softening point. CHEMICAL PROPERTIES Fused Silica is neutral to all halogens and acids irrespective of temperature or concentration except hydro-fluoric and phosphoric acid. Phosphoric acid affects fused silica only at high temperatures and can be concentrated successfully in silica vessels. For all ordinary purposes they can be used with phosphoric acid. Sulphuric - Nitric and Hydrochloric acids or any mixture of these acids - do not affect Fused Silica even at temperatures upto 1000ºC.Strong alkalis react with fused silica. Cleaning of Silica ware regularly can ensure good service. Salts and basic oxides react at elevated temperatures - particularly above their melting point. The extent of reaction is largely determined by the thermal diffusion of impurities into the fused silica. Alkali metals have the highest diffusivity and are the most damaging"
