Abstract

The invention discloses a high breaking resistant glass ceramic disc and a preparation method thereof. The high breaking resistant glass ceramic disc is prepared from the following raw materials by weight part: 27-38 of broken glass, 15-25 of vesuvianite, 14-26 of kaliophilite, 10-15 of chromium slag, 17-29 of basalt, 4-6 of straw ash, 10-15 of titanaugite, 8-16 of dolomite, 9-18 of lazulite, 5-10 of magnesium zirconate, 3-6 of sodium carbonate, 2-3 of cobalt oxide, 3-5 of lithium silicate, and of 5-7 of an assistant. The glass ceramic disc prepared by the invention is prepared by compounding of vesuvianite, kaliophilite, chromium slag, basalt, straw ash, titanaugite, lazulite, magnesium zirconate, lithium silicate and other raw materials, has greatly enhanced mechanical properties, especially the breaking strength and fracture toughness, so that the glass ceramic disc has strong breaking resistance and durability, and is worthy of wide popularization and application.

Description

technical field [0001] The invention relates to a high-shatter-resistant glass-ceramic disc and a preparation method thereof, belonging to the field of ceramic materials. Background technique [0002] Ceramic glass, also known as glass-ceramic, is a kind of composite material combined with crystal phase and glass made through high-temperature melting, molding, and heat treatment. A new type of silicate material, which is a dense, non-porous and uniform mixture composed of crystal phase and residual glass phase. Usually the size of crystals can be from nanometer to micrometer, and the number of crystals can reach 50% to 90%. It has high mechanical strength, low electrical conductivity, high dielectric constant, good machining performance, thermal stability, etc., and is widely used in daily utensils. With the rapid development of science and technology and the continuous improvement of living standards, people's requirements for the quality and performance of glass ceramic ...
