Abstract

PURPOSE:To inexpensively manufacture a high quality quartz glass tube free from residual bubbles by filling high purity glass fine particles in a rubber mold with a central rod placed, press forming them under hydrostatic pressure, and making the resulting preform transparent by heating. CONSTITUTION:SiO2 glass fine particles 12 obtd. by hydrolyzing SiCl4 are filled into cylindrical rubber mold 11 with superior stretchability around central rod 13 of quartz glass, carbon or the like, and mold 11 is set in hydrostatic pressure applying apparatus 14. Pressurized water 16 of about 0.5t/cm<2> is supplied from pressurizer 15. Mold 11 is compressed under uniform hydrostatic pressure with water 16, and particles 12 are converted into a hard porous preform, which is then transparently vitrified by heating with an electric furnace or the like. Rod 13 is removed, and a quartz glass tube having uniform density and contg. fewer OH groups is obtd.
