ABSTRACT:
A process for producing a glass member includes subjecting a silicon, boron, phosphorous or aluminum compound or both a silicon, boron, phosphorous or aluminum compound and a dopant compound to vapor phase reaction to form a fine powder of fused silica, borate, phosphate or alumina or doped fused silica, borate, phosphate or alumina. Then the powder is partially sintered to form a porous glass body which subsequently is immersed in a solution containing a dopant compound thereby depositing the dopant compound on the surfaces of the pores in the glass body. Thereafter, the porous glass body is dried before the pores are collapsed to form the glass member.
