Abstract: PROBLEM TO BE SOLVED: To provide a rapid and cost-effective method for producing SiO2-TiO2 glass having a low coefficient of thermal expansion. SOLUTION: The SiO2-TiO2 glass is produced by the method in which a compact having >40% relative green density is produced. This compact has a principal component comprising dense powdery SiO2 and powdery SiO2-TiO2 or powdery TiO2 or a mixture thereof and contains a titanium-containing component which is converted into amorphous TiO2 in a step for finally sintering the compact at the latest as a secondary component.
