Heading: Science for glass production

It was found that when heated in air to 1100 ° C, the mass of silica glass fiber decreases by approximately 11%. In this case, mainly water is released into the gas phase. In addition to water in the gas phase, hydrocarbons, carbon oxides, and molecular hydrogen were also found in low concentrations. The reason for the appearance of hydrocarbons can be molecules that are adsorbed on the surface of the fiber during their manufacture. The release of water at high temperatures is associated with the destruction of silanol groups. Il. 6, bibliography: 10 titles.
