Making of fused quartz and 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 ...

Silica Sand is quartz that over time, through the work of water and wind, has been broken down into tiny granules. Silica sand deposits are most commonly surface-mined in open pit operations, but dredging and underground mining are also employed. Extracted ore undergoes considerable processing to increase the silica content by reducing impurities.
