Abstract

The invention relates to the technical field of porcelain manufacture and concretely relates to a middle-temperature high-grade daily tableware porcelain and a preparation method thereof. Blank materials of the middle-temperature high-grade daily tableware porcelain comprise kaolin, potassium feldspar, wollastonite, quartz, lithionite, dolomite and calcinedtalc. Glaze materials of the middle-temperature high-grade daily tableware porcelain comprise low temperature transparent frit, feldspar, kaolin, waste glass, fluorite, quartz, zinc oxide, barium carbonate and lithionite. Through adjustment of the blank materials and glaze materials and use of a reasonable formula and specially-produced frit, a sintering temperature is reduced to 1050-1150 DEG C so that a sintering temperature is low, fuel is saved, product stability is high and a production cost is reduced. The glaze materials improve blank whiteness. The middle-temperature high-grade daily tableware porcelain has fine and transparent texture, good light transmittance and a gentle color, has qualitative sense close to that of bone-china, does not release lead and cadmium in a test, is safe for use and has good social and economic benefits.

Description

technical field [0001] The invention relates to the technical field of ceramic manufacturing, in particular to a medium-temperature high-grade daily tableware 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. Existing high-grade tableware usually adopts bone china, which is made of bone meal, kaolin, quartz, feldspar and other raw materials. The firing temperature is between 1300-1350 °C, and the cost of raw materials is high and the firing temperature is high. [0003] With the rising prices of ceramic raw materials and concerns about environmental pollution and other issues, ceramic manufacturers are also transforming towards reducing costs and low-temperature environmental protection during ceramic production. Disclosed is a high-grade porcelain tableware and...
