Foaming glaze and glaze foaming ceramic manufactured by using the same

Abstract

The invention relates to a foaming glaze and a glaze foaming ceramic manufactured by using the same, and belongs to the technical field of ceramics. The foaming glaze comprises 38-42 parts by mass of potassium feldspar, 13-16 parts by mass of kaolin, 5-8 parts by mass of zirconium silicate, 8-11 parts by mass of barium carbonate, 7-12 parts by mass of quartz, 7-9 parts by mass of calcium carbonate, 2-5 parts by mass of zinc oxide, 5-10 parts by mass of talcum, 0.8-1.3 parts by mass of magnesium carbonate, 1-5 parts by mass of silicon carbide, 2-4 parts by mass of neodymium oxide, 8-11 parts by mass of clay, 16-20 parts by mass of borax, 0.2-0.5 part by mass of manganese oxide, 0.2-0.4 part by mass of iron oxide, 18-24 parts by mass of glass powder and 15-21 parts by mass of a low-temperature frit, wherein the low-temperature frit comprises 47-51 parts by mass of borax, 38-41 parts by mass of potassium feldspar, 11-13 parts by mass of calcium carbonate, and 6-9 parts by mass of kaolin. The method includes steps of grinding, adjusting a glaze concentration, glazing, firing, puffing and cooling to obtain the glaze foaming ceramic. The glaze foaming ceramic having color changing effects, and having high acid and alkali resistance, compression resistance and fracture resistance is provided.

Description

technical field [0001] The invention belongs to the technical field of ceramics, and in particular relates to a foamed glaze and glazed foamed ceramics made of the same. Background technique [0002] Glaze is a glassy thin layer covering the surface of ceramics, enamel and other bodies. Generally, the raw materials used in glaze are mineral raw materials such as quartz, feldspar, kaolin, etc. mixed with chemical additives according to a certain ratio. After grinding, glazing, firing Obtained by waiting steps. The surface of the glaze is smooth and shiny, and has the performance of being impermeable and not easy to stain, which can not only improve the physical properties of the ceramic body, but also enhance and beautify the appearance of the ceramic product. [0003] The foamed glaze is fired and foamed to form glazed foam on the ceramic product, which is highly appreciative and has the effect of fire prevention and heat preservation. Can not meet people's needs. The Chi...

[0003] The foamed glaze is fired and foamed to form glazed foam on the ceramic product, which is highly appreciative and has the effect of fire prevention and heat preservation. Can't meet people's needs

The Chinese patent application number 201210190895.0 discloses a foamed ceramic material and its preparation method. Calcium fluoride is used in the co-solvent, which is contrary to the environmental protection advocated by the society today. In the firing and puffing step, the heating rate Slow, long firing time, not conducive to energy saving, and the use of less raw material formula, the ceramic products produced can no longer meet the visual appreciation requirements of today's society.
