Problems solved by technology

Ceramic products currently on the market, especially ceramic cookware, generally do not have high thermal shock resistance. When the product is suddenly heated (or cooled) and expands (or contracts), thermal stress is generated due to the mutual restriction of the deformation of each part. When the thermal stress exceeds the internal bonding force of the product, the product will crack or break, resulting in the product being scrapped and unable to be used again

Abstract

The present invention relates to a heat-resistant porcelain, which comprises the following raw materials by weight: 11-18 parts of Jiangxi black talc washing mud, 22-29 parts of new Yunnan washing mud, 8-12 parts of northern kaolin, 25-35 parts of calcined kaolin, 15-25 parts of mullite, 5-10 parts of Longyan particles, 0.1-0.8 part of phenakite, 0-4 parts of malachite, and 0-9 parts of lapis lazuli. According to the present invention, the heat-resistant porcelain prepared from the heat-resistant porcelain raw materials has advantages of good thermal shock resistance, low shrinkage, low water absorption, high flexural strength and significantly reduced firing temperature, and provides positive significance in the fields of resource saving and environmental protection.

Description

technical field [0001] The invention relates to the technical field of daily-use ceramics, in particular to a heat-resistant porcelain and a preparation method thereof. Background technique [0002] The firing and application of ceramic tableware has a long history in our country. Its various shapes, colorful colors, cool and smooth feel, easy to wash, are deeply loved by Chinese people. Ceramic products currently on the market, especially ceramic cookware, generally do not have high thermal shock resistance. When the product is suddenly heated (or cooled) and expands (or contracts), thermal stress is generated due to the mutual restriction of the deformation of each part. When the thermal stress exceeds the internal bonding force of the product, the product will crack or break, causing the product to be scrapped and unable to be used again. Contents of the invention [0003] The purpose of the present invention is to overcome the shortage of raw materials in the existing...
