High-light-transmittance and high-refraction-index crystalline glass and production process thereof

Abstract

The invention discloses high-light-transmittance and high-refraction-index crystalline glass and a production process thereof. The high-transmittance and high-refraction crystalline glass is preparedfrom, by weight, 30-60% of silicon dioxide, 1-3% of aluminum oxide, 5-25% of titanium dioxide, 1-10% of calcium oxide, 3-10% of magnesium oxide, 3-10% of zinc oxide, 10-20% of barium oxide, 1-3% of lithium oxide, 0.01-0.05% of a decolorizing agent and 0.1-1% of a clarifying agent. The production process comprises the following steps that step 1, the raw materials are classified according to different types; step 2, the classified component raw materials are crushed by a crusher; step 3, the crushed component materials are put into a grinder for grinding. The high-light-transmittance and high-refraction-index crystalline glass and the production process thereof have the advantages that the high-light-transmittance and high-refraction-index crystalline glass can be provided, the lead elementin the crystalline glass is removed, the volatilization of the lead is reduced, the damage to the human body is reduced, the light transmittance and refraction index of the glass are also improved, and the product has stronger market competitiveness and brings higher earnings for enterprises.

Description

technical field [0001] The invention relates to the technical field of high-transparency and high-refraction crystal glass, in particular to a high-transparency and high-refraction crystal glass and a production process thereof. Background technique [0002] With the continuous development of the current society, people's production technology is also constantly developing. The ancient Egyptians first produced glass. Glass is an amorphous inorganic non-metallic material. Generally, it uses a variety of inorganic minerals as the main raw material. It is made of a small amount of auxiliary raw materials. In today's society, people have produced crystal glass for better sales. Generally, crystal glass has high lead content to obtain excellent optical properties. It is widely used for decoration and Tableware and utensils are characterized by better texture, high refractive index of light, more transparent, clear, bright, large dispersion, and low melting temperature.

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a kind of crystal glass with high transparency and high refraction and its production process, to solve the problem that the existing lead-containing crystal glass proposed in the above-mentioned background technology has a relatively high lead content and is difficult to obtain during use. There will be dissolution problems, affecting human health. In addition, lead crystal glass volatilizes into the atmosphere during the melting process and is inhaled by the human body to cause various diseases. With the continuous advancement of science and technology and the enhancement of environmental awareness, lead The poison to the human body and the pollution to the environment have attracted more and more attention from all aspects of the society. Lead-free production is an inevitable trend in the future production of high refractive index crystal glass. The existing processing technology can no longer meet the existing use requirements and The question of consumer choice
