Influence of Layer Thickness in the Mcvd Method on the Composition of Fluorosilicate Glass

The effect of the thickness of deposited porous layers of nanosized silicon dioxide particles in the MCVD method on the efficiency of their doping with fluorine is studied. Its content is determined in the workpieces by the change in the refractive index of the glass. The research results show that the fluorine content is determined by the speed of the burner movement, that is, the duration of the fluorination process of the porous layer of the SiO2 particles rather than its thickness.
