A Note on the Volatility of Silica

JSGT 1934 V18 T222-T224

Fused transparent silica discs suffered no loss in weight when heated in air for 20 hours at 1400°. Experiments in which similar discs were subjected to the action of steam showed that in 20 hours at 1300° the loss in weight was negligible, but in 20 hours at 1400° and in 4 hours at 1500° the loss was small but appreciable. The surface in contact with the steam became slightly pitted and glossy.
