Problems solved by technology

[0002] At present, the bone china on the market has good light transmittance, but its flexural strength is low, and because the support point of the blank is lowered under high temperature and load, it is easy to soften and deform, so a second firing process (that is, a high temperature biscuit firing process must be adopted) , a low-temperature glaze firing), high energy consumption and high cost; and high-silicon reinforced porcelain, high-alumina reinforced porcelain, magnesium reinforced porcelain, etc., have high flexural strength, but poor light transmission

Abstract

The invention discloses a sclerotin intensification ceramic and manufacturing technique, which comprises the following elements: dragon rock wash mud, Hunan feldspar, Guizhou clay, alpha-alumina powder and synthetic bone meal. The manufacturing technique comprises the following steps: blanking; making blank body; preparing frit; making magentify step. The sclerotin intensification ceramic realizes the primary firing, which reduces the energy and improves the transverse strength.

Description

technical field [0001] The invention relates to a reinforced porcelain and its production process, in particular to a bone reinforced porcelain and its production process. Background technique [0002] At present, the bone china on the market has good light transmittance, but its flexural strength is low, and because the support point of the blank is lowered under high temperature and load, and it is easy to soften and deform, a second firing process must be adopted (that is, a high temperature biscuit firing process). , a low-temperature glaze firing), high energy consumption and high cost; and high-silicon reinforced porcelain, high-alumina reinforced porcelain, magnesium reinforced porcelain, etc., have high flexural strength, but poor light transmission. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a bone-reinforced porcelain and its production process. The produced product not only...
