Title: Production of sintered quartz glass molded article
Inventor: TAGAWA KOJI
IPC: C03B8/00
Filed: 1998-09-28
Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a sintered quartz glass molded article, capable of giving the article having enhanced light transmittance by sintering a false quartz powder molded article consisting mainly of quartz glass in an atmosphere having a specific hydrogen pressure or larger and a specified temperature or higher. SOLUTION: A false quartz glass molded product is sintered in an atmosphere having a hydrogen pressure of >=10-2 Pa and a temperature of >=1,773K. When hydrogen gas is contained in the sintering atmosphere, SiO2 is reacted with hydrogen to produce SiO and SiH4, which are scattered from the quartz glass because of having high volatility. Since crystalline quartz such as cristobalite or β-quartz which is by-produced on the sintering treatment do not leave on the surface of the quartz glass, the transparent molded article having a high light transmission is obtained. When the atmosphere comprises pure hydrogen gas having a high hydrogen gas pressure, the reaction often excessively proceeds to largely consume SiO2. Thereby, when the atmosphere comprising a gas mixture of hydrogen gas with an inert gas is used as the sintering atmosphere and further when the sintering temperature is controlled, the consumption of the quartz glass due to the scattering of the SiO2, SiH4, etc., can be inhibited.
