Abstract

The invention belongs to the technical field of ceramics for daily use, and particularly relates to a high-silicon ceramic with quartz as a base material and a preparation method. A product comprisescomponents in percentage by weight as follows: 84%-88% of silica, 7%-11% of alumina, 3%-3.5% of potassium oxide, 0.5%-1.0% of sodium oxide, 0.3%-0.4% of calcium oxide, 0.07%-0.11% of iron oxide and 0.2%-0.3% of magnesium oxide; the high-silicon ceramic with quartz as the base material has density being 2.5-2.55 g/cm<3> and breaking strength being 120-140 Mpa, and whiteness of a porcelain body is not lower than 80. The defect of ceramic burst of a product is overcome, and heat stability of the product is improved.

Description

technical field [0001] The invention belongs to the technical field of daily-use ceramics, and in particular relates to a high-silicon ceramic with quartz as a base material and a preparation method thereof. Background technique [0002] At present, the daily-use porcelain produced in our country is mainly feldspar porcelain, bone ash china, magnesia porcelain, etc. Afterwards, the formulas of various types of porcelain are fused with each other to complement each other, and then feldspar bone china and feldspar magnesia porcelain are produced. kind. And the common point in these porcelain kind all is to form with the feldspar of 20~30%, the plastic clay or kaolin of 40~60%, the quartz below 15%. Wherein, the consumption of plastic clay or kaolin as the main raw material is relatively large. Therefore, it is necessary to develop non-aluminosilicate daily-use ceramic material systems, change the current dependence of daily-use ceramic production on clay, and find cheap and ...
