FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing highly pure and defect-free quartz glass using a sol-gel technology. Sol is obtained by hydrolysis of tetraethyl orthosilicate with hydrochloric acid solution. Silica sol with particle size of less than 100 nm is added to the sol. A structure-forming agent in form of amides of organic acids is added at the gel-formation step. The formed gel is then held in a dispersion medium and heat treatment is carried out at temperature of 1000-1050°C.
EFFECT: low synthesis temperature of quartz glass and fewer impurities in the obtained glass.
