Problems solved by technology

[0005] In order to solve the problem of thermal stability deviation of Dehua white porcelain, researchers tried to add petalite, spodumene and other raw materials into white porcelain blanks, but the effect was not obvious, mainly reflected in the following two aspects: (1 ) When the thermal stability of ceramics is improved, it is difficult to meet the quality requirements of Dehua white porcelain; (2) under the requirements of light transmittance and whiteness, its thermal stability is difficult to meet the requirements of the national standard for daily-use porcelain

Abstract

The invention belongs to the technical field of daily use ceramics, and particularly relates to a high-thermal stability and high-whiteness ceramic and a preparation method thereof. The high-thermal stability and high-whiteness ceramic comprises a high-thermal stability and high-whiteness blank and a transparent glaze, and the high-thermal stability and high-whiteness blank comprises Inner Mongolia potash feldspar, Lincang kaolin, Longyan kaolin, bentonite and a low expansion agent; and the transparent glaze comprises, by weight, Jiangxi potash feldspar, quartz, Longyan kaolin, heavy calcium,calcined zinc oxide, barium sulfate, calcined talcum powder and a regulator. The prepared ceramic blank and glaze are well combined by adopting the method, so the ceramic of the invention has delicatetransparent porcelain and a smooth and bright glaze surface, has a whiteness reaching 81 or more, and achieves thermal exchange at 200-20 DEG C two times without cracking due to high thermal stability; and the preparation method has the advantages of easily availably preparation raw materials, wide firing range, simple preparation process and high product yield, and is suitable for being promotedand applied to the field of daily use ceramics.

Description

technical field [0001] The invention belongs to the field of glaze preparation, and in particular relates to a ceramic with high thermal stability and high whiteness and a preparation method thereof. Background technique [0002] Dehua, together with Jingdezhen and Liling, is known as the "Three Ancient Porcelain Capitals of China". Since the Song Dynasty, Dehua white porcelain has become an important export product of the "Maritime Silk Road" and has been sought after by European nobles. In the Ming Dynasty, porcelain masters produced a kind of warm milky white porcelain that was as fat as jade. The French praised Dehua white porcelain as "BLANC DE CHINE" at that time, and they thought it was "Chinese porcelain". top grade". Dehua white porcelain is well-known at home and abroad for its unique porcelain quality and craftsmanship, and has the reputation of "the world's white porcelain looks at China, and Chinese white porcelain looks at Dehua". [0003] Today, the populari...
