Reaction of Fused Silica With Hydrogen Gas [PDF]
Journal of the American Ceramic Society, 1982 Fused silica and flowing hydrogen gas react in the experimental temperature range of 1200° to 1400°C to form SiO and H 2 O vapors. Above a critical flow rate of hydrogen gas, the reaction rate is independent of gas flow rate and is not transport‐controlled.
