Abstract
PURPOSE:To obtain the titled glass which consists of SiO2-ZrO2-base two components glass having a specified range of ZrO2 content and is excellent in transmission characteristics of ultraviolet rays and is extremely low in thermal expansion coefficient. CONSTITUTION:A soln. obtained by mixing e.g. commercial zirconium butoxide with methyl orthosilicate in the mixing rate respectively shown in a table 1 is dissolved in ethanol having same volume. The raw material soln. obtained by slowly adding prescribed amount of pure water thereto is heated to obtain gel. Then this gel is dried and thereafter heat-treated at 900-1100 deg.C to obtain the aimed glass. This glass is excellent in transmission characteristics of ultraviolet rays as shown in the table 1 and has thermal expansion coefficient showing extremely low value such as 1/10 or below of silica glass. Further the glass of this invention consists of SiO2-ZrO2-base two components glass and 0.2-10wt.% ZrO2 must be contained therein.
