Abstract

The invention belongs to the technical field of ceramic and particularly relates to a preparation method of high-whiteness bone ceramic. The invention aims to solve a technical problem of providing the preparation method of the bone ceramic which is good in color and high in whiteness. To solve the technical problem, the invention provides the preparation method of the high-whiteness bone ceramic. The preparation method includes following steps: a. preparing a blank material; b. preparing a glaze; c. performing a gradedly low-temperature biscuiting process; d. performing a glazing process; e. performing a secondary gradedly temperature-increasing firing process; and f. performing a gradedly temperature-decreasing process. The prepared bone ceramic is good in color and high in whiteness, a cracking phenomenon during the firing process of the bone ceramic is prevented effectively and a yield is greatly increased.

Description

technical field [0001] The invention belongs to the technical field of ceramics, and in particular relates to a preparation method of high-whiteness bone ceramics. Background technique [0002] Bone ceramics is the abbreviation of bone china, the scientific name bone china. It is a kind of porcelain made of animal bone charcoal, clay, feldspar and quartz as the basic raw materials, which are fired twice by high-temperature biscuit firing and low-temperature glaze firing. Bone ceramics are also an environmentally friendly green consumer product. Bone ceramics are recognized as the highest grade porcelain in the world. [0003] Features of bone ceramics: 1. Beautiful appearance: the porcelain is delicate and transparent, the shape is beautiful and elegant, the color surface is moist and bright, and the flower surface is colorful; 2. High grade: produced in England, it has long been the special porcelain for the British royal family and nobles. It is currently the only high-g...
