Abstract

The invention provides a high-grade magnesium household porcelain, which relates to the technical field of ceramics. The blank of the household porcelain comprises the following components in percentage by weight: 30-50% of calcined white talc, 20-40% of Guangfeng black talc, 10-20% of kaolin, 5-10% of petalite and 2-5% of zirconium silicate. The glaze of the household porcelain comprises the following components in percentage by weight: 40-55% of feldspar, 15-22% of quartz, 10-15% of calcite, 5-10% of calcined talc, 3-8% of ZnO and 5-10% of kaolin. The appearance quality and the performance of the high-grade magnesium household porcelain are superior to those of bone china and reinforced porcelain, and the high-grade magnesium household porcelain reaches and exceeds various standards of the high-grade household porcelain. The performance indexes are as follows: the breaking strength is more than or equal to 200MPa, the whiteness is more than or equal to 84%, the light transmittance is more than or equal to 80%, and the water absorption is less than or equal to 0.1%. And the heat stability is as follows: cracking is avoided after three times of heat exchange at 20-200 DEG C.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a high-grade magnesia daily-use porcelain and a manufacturing method thereof. Background technique [0002] As early as the end of the 18th century, Britain used talc as the main raw material to make magnesia porcelain, also known as talc porcelain. Steatite porcelain is often used to make porcelain for high-frequency insulating devices because of its low dielectric loss, high mechanical strength, and electromechanical properties between high-alumina porcelain and ordinary porcelain. [0003] In the 1980s, Shandong, my country developed a kind of talc porcelain that can be applied to daily-use ceramics. It has excellent characteristics such as high whiteness, high strength, and high transparency. However, due to its poor process performance, narrow firing range, and late aging, three major technical problems are difficult to overcome, and it has not been able to achieve industr...
