Problems solved by technology

Fluorite or sodium fluorosilicate is used as an opacifying agent, and fluorine-containing substances will volatilize during the glass melting process, especially when the flame furnace is used to produce opalescent glass, the volatilization rate can reach 6% to 10%, which seriously pollutes the environment and damages the environment. human health
Moreover, the health problems of fluorine-containing opal glass products when heated and used are also worrying. Fluorine is one of the harmful substances, and its usage should be limited
The addition of a large amount of oxides can have an opacification effect. However, when the amount is large, the glass will be difficult to melt and the cost will also increase.

Description

technical field [0001] The invention belongs to the field of glass products, and in particular relates to a low-fluorine opal glass product and a preparation method thereof. Background technique [0002] Opalescent glass is an artificial glass material that produces an opacifying effect under the action of light scattering by tiny particles in fluoride. It is a white translucent glass containing highly dispersed crystals made of transparent liquid glass. Introduce some low-solubility opacifiers such as fluoride, chloride, phosphate, sulfate, etc. into the batch material. These substances dissolve in the glass liquid at high temperature, and precipitate one or more tiny particles of crystal when the temperature is lowered. Light entering its interior is scattered by these particles, creating an opalescent effect. The degree of opacification depends on the dispersion of precipitated substances and the difference in refractive index between them and the host glass. [0003] G...
