Abstract: PURPOSE:To obtain the silica glass enhanced in high-temp. viscosity and heat stability in the glass contg. fine silica crystals by growing the silica crystal into a needle crystal of specified length with a ceramic nucleating agent as the nucleus. CONSTITUTION:A nonreactive ceramic fine particle having >=m.p.2000 deg.C is mixed with a silica glass powder or a silica crystal powder, and the mixture is heated and melted to form a ceramic fine particle-dispersed silica glass gob. The gob is heat-treated at >=1000 deg.C to deposit a silica needle crystal, and a partially crystallized glass contg. 5-50vol.% of the silica needle crystal having <=100mum length in the silica glass matrix is obtained.
