Problems solved by technology

[0003] However, as humans have higher and higher requirements for the color, environmental protection and health performance of blue-and-white glazed ceramics, traditional blue-and-white glazed ceramics can no longer meet human needs. Scientists are constantly optimizing the composition of ceramic bodies and glazes , in order to improve the physical and chemical properties of ceramics such as color rendering, hardness and stability

Abstract

The invention discloses blue and white glazed porcelain. A porcelain blank consists of kaolin, natural clay, talc, feldspar, alumina micro-powder, silicon nitride, barium carbonate and wollastonite. A glaze for the porcelain consists of zinc oxide, cobalt oxide, quartz, limestone, lithium feldspar, ulexite, silicon carbonate, silicon nitride, iron sesquioxide, tin dioxide, zinc borate, montmorillonite, carboxymethylcellulose sodium and sodium humate. According to the blue and white glazed porcelain, the compositions of the porcelain blank and the glaze are optimized, so that the coloring effect and the physical and chemical performance such as hardness and stability of the porcelain are improved.

Description

technical field [0001] The invention belongs to the field of ceramics, in particular to blue and white glaze ceramics. Background technique [0002] Ceramics is an ancient and traditional industry in my country. With the development of science and technology, blue and white glaze ceramics can be seen everywhere in daily life. Ceramics are materials and various products made of clay as the main raw material and various natural minerals through pulverization, mixing, molding and calcination. People make a kind of pottery clay and fire it at a high temperature in a special kiln called ceramics, which is the general term for pottery and porcelain. The traditional concept of ceramics refers to all artificial industrial products that use inorganic non-metallic minerals such as clay as raw materials. It includes various products made of clay or a mixture containing clay through kneading, shaping, and calcination. [0003] However, as humans have higher and higher requirements f...
