The invention specifically relates to a daily-use glass-ceramic with a smooth surface and a preparation method thereof, and belongs to the technical field of daily-use glass-ceramic and its preparation. The daily-use glass-ceramic comprises a glass-ceramic body and a transparent layer covering the surface of the glass-ceramic body: the raw material of the glass-ceramic body consists of silicon dioxide, boron oxide, metal oxide, sodium fluorosilicate, pentoxide Phosphorus and additives; the raw material components of the transparent layer are refined potassium feldspar powder, refined kaolin, refined quartz, zinc oxide, and magnesium carbonate. The preparation method is that the raw materials of the glass-ceramic body are smelted first, then pressed into shape, then polished, then glazed, and then polished to obtain the finished product. The invention solves the problems of poor quality and low yield of daily-use glass ceramics in the prior art, and the prepared daily-use glass-ceramics has the advantages of stable quality, high quality, smooth surface, uniform color and high yield.
Description
technical field [0001] The invention relates to the technical field of daily-use glass ceramics and its preparation, in particular to a daily-use glass ceramics with a smooth surface and a preparation method thereof. Background technique [0002] Glass-ceramics, 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. Glass ceramics are widely used in machinery manufacturing, optics, electronics and microelectronics, aerospace, chemistry, industry, biomedicine and construction and other fields. [0003] Glass-ceramic is a new type of polycrystalline silicate material crystallized by glass under the action of catalyst or crystal nucleating agent. It is a dense, non-porous and uniform mixture composed of crystalline 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...
