Ceramic product fired at medium-low temperature and manufacturing process thereof

Abstract

The invention provides a ceramic product fired at a medium-low temperature and a manufacturing process thereof. The ceramic comprises a blank body and a glaze layer applied on the blank body. The ceramic is characterized in that the blank body is prepared from the following raw materials in parts by weight: 50-70 parts of dolomite, 10-20 parts of quartz, 10-25 parts of feldspar, 2-5 parts of cobalt oxide, 15-20 parts of diatomite, 5-20 parts of clay, 8-15 parts of calcium silicate and 4-8 parts of konjac glucomannan; the glaze layer is prepared from the following raw materials in parts by weight: 28-32 parts of quartz, 26-30 parts of feldspar, 14-18 parts of borax, 6-10 parts of dolomite, 8-12 parts of kaolin, 3-7 parts of zinc oxide, 5-10 parts of sodium silicate, 5-10 parts of silicon oxide, 4-6 parts of boron oxide and 5-10 parts of pigment. The ceramic product fired at the medium-low temperature provided by the invention has the advantages that the water absorptivity is lower than1% and the problem of low water absorptivity of the ceramic fired at the medium-low temperature is solved.

Description

technical field [0001] The invention belongs to the technical field of ceramic production technology, and in particular relates to a medium-low temperature fired ceramic product and a manufacturing process thereof. Background technique [0002] Medium-temperature ceramics refer to ceramics with a firing temperature of about 1000-1200°C. According to the main chemical composition of the material, they can be divided into oxides. Low-temperature ceramics refer to ceramics with a firing temperature of about 700-900°C. The firing temperature of medium and low-temperature ceramics is Low cost, low energy consumption, and short firing time. At the same time, it has the disadvantages of wood stagnation, rough porcelain, brittleness, and high water absorption. Therefore, it is necessary to explore a low-medium firing temperature and low water absorption. Ceramics are of great value. Contents of the invention [0003] Based on the above prior art, the present invention provides a ...
