Abstract

PURPOSE:To easily control the depant content and to efficiently manufacture the titled homogeneous transparent glass by adding GeO2-base dopant oxide to the surfaces of fine silica glass particles in the form of a solid soln. and sintering them. CONSTITUTION:An easily oxidizable Si compound is thermally oxidized or hydrolyzed in a flame to produce fine silica glass particles. The particles are put in a rotary reactor and exposed to an atmospheric gas contg. an easily oxidizable Ge compound and O2 at a high temp. to add GeO2-base dopant oxide to the surfaces of the glass particles in the form of a solid soln. The resulting fine doped silica glass particles are sintered and converted into transparent glass to manufacture a transparent glass body. By sealing this glass body as a core material in a quartz glass pipe and drawing them, a superior optical fiber is obtd.
