ABSTRACT:
A method of producing a cast fused silica product includes grinding fused silica particles to have a first particle size and to form an aqueous slurry. A fused silica aggregate is provided having a second particle size greater than the first particle size. A first amount of the aqueous slurry is dried to form dried fused silica particles and the dry fused silica particles are ground to have a third particle size intermediate to the first and second particles sizes. A second amount of the aqueous slurry, the fused silica aggregate and the ground fused silica particles are admixed to form a casting mix.
