Opacifier - Wikipedia

Fluorides of aluminium, calcium, barium, and magnesium can be used with suitable heat treatment. Tin oxide can be used, but zirconia and titania give better results; for titania, the appropriate resulting particle size is between submicron to 20 µm. Another desirable opacifier is zinc oxide. Opacifiers must also form small particles in the system.
