Embodiment Construction
[0032] The bone jade porcelain mud of the present invention is mainly prepared from 45-55wt% purified bone meal, 30-40wt% kaolin and 20-25wt% potassium-sodium feldspar, wherein bone powder, kaolin and potassium-sodium feldspar The particle size is 250-300 mesh. Wherein, the bone meal is a powder obtained by purifying and pulverizing bovine bone or sheep bone.
[0033] The preparation method of the bone jade porcelain mud of the present invention is realized through the following steps:
[0034] 1. Preparation of bone meal
[0035] A. Carry out conventional calcination on the dried bovine or sheep bone, and burn it from normal temperature to about 1000°C within 4-6 hours, and then reduce and calcinate the bovine or sheep bone with a reducing flame at 1000-1350°C 1- For 3 hours, the divalent iron in the bovine bone or sheep bone is reduced to ferric iron to obtain the initial bone block;
[0036] B. Forge the initial bone blocks obtained above into fine pieces, then ball mill...

Abstract
The invention discloses a bone jade porcelain pug and a preparation method thereof. The bone jade porcelain pug is mainly prepared from 45-55 wt% of purified bone powder, 30-40 wt% of kaolin and 20-25 wt% of potash feldspar and soda feldspar; a bone jade porcelain prepared by the pug not only has high-stability crystal structures of calcium phosphate, silicon dioxide and aluminum oxide, but also contains new low-melting-point substances such as sodium silicate, potassium silicate and a small amount of calcium silicate, and molecular gaps of an blank body are just filled up with the low-melting-point substances so as to obtain an exquisite porcelain product, namely, the bone jade porcelain with high whiteness, warm and mold color, fine and smooth porcelain and high transparency. According to the preparation method, cattle and sheep bones are used as a main raw material, so that rare mineral materials are greatly saved on resources, and the resources can be saved by 90% and the energy consumption can be lowered by 80% per ten thousand output value. The bone jade porcelain pug industry is an ecology-friendly, resource-saving and sustainable industry, and the plug has very high market competitiveness, and can bring comprehensive social benefits.
Description
technical field [0001] The invention relates to the field of porcelain, in particular to a new type of porcelain-bone jade porcelain clay and a preparation method thereof. Background technique [0002] my country has a history of thousands of years of making ceramics. In the formula of ceramic raw materials, the theory of using silicate and alumina as ceramic supports has been used for thousands of years. Chinese jade porcelain is created in the field of ceramics with its warm color and fine quality. It has created immortal myths, legends and brilliance, so ceramic raw material technology has always been a subject of silicate research in China. [0003] About 300 years ago, ceramic craftsmen in Western Europe, especially the United Kingdom, began to use animal ashes as raw materials to produce the only porcelain in the world that was not born in my country-bone china. Calcium and alumina are used to make ceramics. Bone China has the characteristics of high whiteness and good ...
