ABSTRACT:
A method of producing pure and dense amorphous fused synthetic silica. Silica of desired purity is wet pelletized or agglomerated to form particles having an average particle size of between about 5 and 2500 microns. These particles are calcined to volatilize impurities and increase density to at least about 0.9 g/cm.sup.3. Calcined particles are classified by size or reduced in size if desired or needed by grinding in such a way that the purity of the product is maintained.
