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 ...
