Title: METHOD FOR MANUFACTURING GLASS MEMBER
Abstract:
Provided is a method for manufacturing a glass member by firing a glass powder characterized by including: a blending step of dry blending a filler powder, in which primary particles having a primary particle size of 50 nm or less are aggregated, with a glass powder, in which the average particle size D50 is larger than the primary particle size of the filler powder, to obtain a mixture; and a firing step of firing the mixture. The filler powder is contained in an amount of 0.01 to 10 wt% with respect to the total amount of the glass powder and the filler powder, and the blending step is carried out by blending while applying a force of 1 N/cm2 or greater. In this method, the generation of air bubbles can be suppressed during firing.
