Abstract

The invention discloses crystal glass and a preparation process thereof, and relates to the field of manufacturing of crystal glass. The crystal glass is prepared from the following raw materials: SiO2, ZnO, Al2O3, CaO, Li2CO3, B2O3, SrO, Y2O3, MgO, SnO and modified mordenite powder. The preparation process of the crystal glass comprises the following steps: crushing and mixing the raw materials to obtain powder; then melting the powder into melted liquid; then carrying out standing and clarification treatment on the melted liquid; finally, pouring and molding a clarified material, and carrying out annealing treatment and air cooling to obtain the crystal glass. According to the crystal glass disclosed by the invention, the components do not contain lead and barium, and requirements of high refractive index, high chromatic dispersion coefficient and high transparency are met through changing components and a manufacturing process under the conditions of greenness and environment friendliness; a finished product has the advantages of high strength, corrosion resistance, high temperature resistance and excellent performance.

Description

technical field [0001] The invention relates to the field of crystal glass manufacturing, in particular to a crystal glass and a preparation process thereof. Background technique [0002] In the prior art, traditional leaded glass frits are mostly used in the production technology of crystal glass, and through long-term production practice at home and abroad, it is proved that crystal glass with lead content of 24% has higher transparency and refractive index. Lead oxide (PbO) and barium oxide (BaO), as the main raw materials of traditional crystal glass, can not only increase the refractive index of the glass, but also increase the dispersion rate of the glass. In existing glass formulations, in order to increase the refractive index and dispersion rate, the content of PbO and BaO in the glass composition is often increased. When lead crystal glass products are used, especially as water utensils, wine utensils, and tableware, the lead dissolved in them is very toxic and en...
