Problems solved by technology

At present, the temperature difference in water exchange of bone china products produced in China is mostly below 140 °C, and some are even below 100 °C. Even high-quality bone china products can only exchange temperature differences in water of 160 °C, and their thermal shock resistance is poor. Influenced the promotion and use of bone china

Abstract

The invention provides a novel preform body for bone porcelain and a preparation process of the preform body. The novel preform body for bone porcelain comprises the following components in percentage by weight: 50-55% of bone meal, 24-28% of kaolin, 9-11% of quartz, 8-10% of feldspar, 0.38-0.52% of lithium chinastone, 0.8-1.6% of zircon sand and 0.4-0.8% of nano-aluminum oxide. The preparation process comprises the following steps: mixing various ground materials with proper granularity to prepare the preform body, and calcining once again before the bone meal is mixed. The preform body prepared in the invention is good in thermal shock resistance, high in strength, uniform in structure, compact in toughness and excellent in overall performance.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a novel blank for bone china and a preparation process thereof. Background technique [0002] Bone china, formerly known as bone china, is a high-grade porcelain produced in the UK. It is generally referred to as bone china. It is made of traditional ceramic raw materials mixed with animal bone ashes and fired at high temperature. Bone china is a kind of soft porcelain, and the animal ashes used are mostly high-quality bovine bones. Therefore, bone china is fine in quality, smooth in glaze, soft in luster, like fat like jade, very elegant and luxurious, and has a high quality. Transparency and certain mechanical strength. Its owner has the reputation of "thin as paper, bright as mirror, white as jade, and sound like chime". In daily-use ceramics, bone china is widely used, and is recognized as the highest-grade porcelain in the world today, and is deeply loved by consumers. ...
