Abstract

The invention discloses an oxidized white china clay which comprises the following components by weight ratio: 20-25 parts of feldspar, 15-20 parts of quartz, 5-10 parts of raw ores, 40-45 parts of kaolin, 5-10 parts of white china powder and 0.005-0.008% of cobalt blue pigment. The invention also discloses a preparation method of the oxidized white china clay. According to the oxidized white china clay and the preparation method, the waste white china is processed into another man-made high-quality barren material, so that the source of the high-quality barren material can be partially increased and large economic benefit can be produced at the same time; a trace amount of cobalt blue pigment is added in the clay according to weight proportion, so that the china clay is bluish white under oxidation burning atmosphere, the chinaware whiteness is increased by 4-8% and the shrinking percentage is reduced by 2-3%.

Description

technical field [0001] The invention belongs to the technical field of ceramics, and specifically refers to an oxidized kaolin mixed with waste white porcelain powder and trace green materials and a preparation method thereof. Background technique [0002] With the development of society and the improvement of people's living standards, more and more waste white porcelain is produced in the daily-use white porcelain industry. It is estimated that discarded white porcelain accounts for 20-30% of daily-use white porcelain production. Simple and crude waste accumulation or landfill disposal methods not only pollute the environment but also cause waste. Therefore, the waste white porcelain is collected and processed for reuse to promote the sustainable development of the daily-use white porcelain industry. Contents of the invention [0003] In order to promote the sustainable development of the daily-use white porcelain industry, the invention provides an oxidized white chin...
