WebSodium silicate reaches flow point at 730 to 870 °C, and starts to soften at 550 to 670 °C, depending on the compound’s molar ratio. Aqueous solutions of silicates have a melting point that is slightly higher than water (IPCS, 2004). Boiling Point Boiling point not applicable for solid, anhydrous silicates, because they are glasses. Web"Chemically most glasses are silicates. Silica by itself makes a good glass (fused silica), but its high melting point (1723 C or 3133 F) and its high viscosity in the liquid state make it difficult to melt and work." 1723 C: Science and Technology Desk Reference, The Carnegie Library of Pittsburgh Science and Technology Department: 2000.
