Abstract

PURPOSE:To obtain a glass layer of uniform composition by putting the gas containing volatile germanium halide, antimony pentachloride and oxygen into a reacting tube and applying high-frequency output from the outer side. CONSTITUTION:Electric discharge is caused in a reacting tube by applying high- frequency output to the gas containing volatile germanium halide, for example, germanium tetrachloride etc., antimony pentachloride and oxygen. The glass layer comprising essentialy germanium oxide and antimony oxide is formed on the inside surface of the reacting tube. The molar ratio between the germanium and antimony in the gas is selected freely. The pressure in the tube is about 0.1-100torr. The high-frequencies to be applied are microwaves, for example, high frequencies of about 245GHz or 1-30MHz, and the applied output thereof is suitably selected. The material of the reacting tube is of glass of various properties close to the thermal properties and mechanical properties of the glass formed. Thereby, the infrared light transmitting body blank material of the uniform composition is obtained from the mixed gases.
