ABSTRACT:
A method for producing a high-purity silica glass powder by calcining a high purity silica gel powder, wherein a vertical-type moving bed apparatus equipped with a heating means is used in a moving bed system such that the feed silica gel powder is continuously supplied from an upper portion of the apparatus and discharged from a lower portion of the apparatus, and wherein a small amount of gas is blown to flow from a lower portion of the moving bed towards an upper portion of the moving bed, and the calcination is conducted at a temperature of from 1,000.degree. to 1,300.degree. C.
