High purity silica powder formed from a sol-gel process is made from a quantity of an industrial grade hydrolizable silicon organometallic substance mixed with a quantity of an industrial grade organic solvent miscible in said organometallic substance and with a quantity of an acidified water having a pH less than 2 to form a solution. The solution is heated, then dried to form a gel, milled, and calcined to form the pure silica powder and the pure powder used to form encapsulated micro-miniature circuits.
