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 ...

Because of the high temperature of the plasma, this process is best suited to produce fluorine doped fused silica. The achievable maximum content of fluorine in silica is a function of deposition temperature. There is a limit to the maximum fluorine content, because fluorine also etches away fused silica.
