摘要

Manufacture of transparent surface layer-containing silica glass component involves preparing a slurry of silica particles and a liquid, casting slurry into liquid-impermeable form, cooling the liquid to cooling temperature of freezing point to form semi-frozen blue material, drying frozen material into blue green component by heating at heating temperature below boiling point of liquid, sintering green component to white porous component, and sealing white component to closed porous surface by introducing energy.
