Making of fused silica Heraeus

Two step fused silica production. In this process, soot is deposited on a rotating bait rod (outside vapor deposition; OVD) or on the end of a rod that is pulled upwards (vapor axial deposition; VAD). The soot accumulates and forms a porous body with a density that is less than 25% of that of fused silica. This porous body is then vitrified in

US5004488A Process for producing high purity fused

High purity fused silica particles are made by heating relatively low density silica flour in a high temperature flame. The silica flour feed rate, flame temperature, and collection zone temperature are adjusted to produce an aggregate of surface-bonded fused silica particles. The aggregate is shaped like a honeycomb and can be ground autogenously without introducing impurities into the final
