Abstract

The invention relates to a glass ball, particularly relates to a lead-free potassium barium glass ball and a production process thereof, and belongs to the technical field of glass material. The glass ball comprises the raw materials by the mass percentage: 1.05-1.45% of sandstone, 6.0-10.0% of quartz sand, 8.5-12.5% of bauxite, 10.5-12.50% of limestone, 8.5-10.5% of broken glass, 15.2-16.3% of ascharite, 0.5-1.0% of titanium dioxide, 0.5-2.0% of niobium carbide, 1.52-1.56% of fluorite, 0.45-0.55% of a clarifying agent, and the balance pyrophyllite. While the glass ball is guaranteed to have the advantages of being high in whiteness, glittering and translucent, high in gloss, rich in refractive index, toughness and the like, the chemical stability, the thermal stability and the mechanical strength of the lead-free potassium barium glass ball are improved, and the crystallization tendency of the lead-free potassium barium glass ball is reduced, and the cost of production is greatly reduced.

Description

technical field [0001] The invention relates to a glass ball, in particular to a lead-free potassium-barium glass ball and a production process thereof, belonging to the technical field of glass materials. Background technique [0002] Existing vessel glass frit side is mainly soda-lime glass. With the continuous improvement of people's living standards and aesthetics, the requirements for high-grade glassware are getting higher and higher, not only requiring beautiful appearance, but also practicality and good performance, long service life and low production cost. The vessel glass frit in the prior art cannot take into account the requirements of all aspects, so the production of glass with high whiteness, crystal clear, high gloss, high refractive index, toughness, bright and flawless, and unique properties such as chemical stability and thermal stability It is expected to be a problem that the industry needs to solve urgently. Contents of the invention [0003] The o...
