Abstract: PURPOSE:To obtain the titled molded article having high resistance to devitrification at a low cost, by coating a molded article of fused quartz with ultra- fine powder of high-purity amorphous silica using a colloidal solution obtained by the hydrolysis of silicon tetrachloride. CONSTITUTION:A molded article 1 of fused quartz having a porosity of about 4-20% is immersed in a colloidal solution prepared by the hydrolysis of silicon tetrachloride. Ultra-fine particles of high-purity amorphous silica 3 having particle diameter of about 0.01mum are brought into the pore 2 by capillary action.
