Abstract

The invention relates to a preparation and application method of high whiteness, high light transmittance and high plasticity ceramic blank mud, which uses Linchuan talc, phlogopite, orthoclase and American fairy water as raw materials, and undergoes raw material pretreatment, batching, ball milling, Aged, sieved, iron-removed, dehydrated, and smelted to obtain a ceramic body slime with a plasticity index greater than 20, and the ceramic body mud has a whiteness greater than 84 after molding, drying, biscuit firing, water replenishment, glazing, and high-temperature firing. Ceramic products with light transmittance greater than 7.5% / 2mm. The invention adopts common mineral raw materials and chemical raw materials for specific proportioning, and modifies the Linchuan talc, so that the green body has high whiteness, strong light transmittance, good plasticity and wide sintering range, and can also make The green body will not be deformed when it is fired at a high temperature of 1240-1310°C. It solves the shortcomings of high difficulty in production, complex molding process and narrow firing temperature range of high-whiteness and high-transparency ceramics, so it has broad market prospects.

Description

technical field [0001] The invention belongs to the technical field of traditional ceramic manufacturing, and in particular relates to a preparation and application method of high-whiteness, high-transparency, and high-plasticity ceramic mud, which is suitable for manufacturing various high-grade daily-use porcelain and art porcelain. Background technique [0002] The whiteness and light transmittance of daily-use ceramics are an important indicator that affects the quality of ceramic products. Since 1956, Jingdezhen has passed a large number of scientific experiments, absorbed the refinement of ceramic science at home and abroad, and finally adopted porcelain composed of Jiangxi Linchuan talc. The body and glaze make the whiteness and transparency of porcelain surpass the historical peak, and reach the highest level of Chinese porcelain manufacturing beyond the international and Chinese history. The display porcelain of the important heads of the Chinese government and the ...
