Abstract

The invention discloses a high-calcium ceramic and a preparation process of the high-calcium ceramic. According to the preparation process, the low-price calcium mineral calcite or stalactite is adopted to replace the animal bone ash to be directly used for preparing the high-calcium ceramic, thus the conventional bone china formulation design scope is broken through, the resources of raw materials for producing high-level ceramic are enriched, and the production cost is greatly reduced; and in addition, the preparation process is simple, the quality is easily controlled, the energy is saved, and the production cost is further reduced. The high-calcium ceramic prepared by the preparation process disclosed by the invention is crystal clear and soft and smooth, and can be used as the substitute of the conventional bone chain.

Description

technical field [0001] The invention belongs to the technical field of ceramics, in particular to a high-calcium ceramic and a preparation process thereof. Background technique [0002] The formation of bone china mainly depends on silica, alumina and calcium oxide, and the higher the content of calcium oxide, the better the color. In nature, there are not many sources of calcium oxide, so the ashes of animals are chosen as the source of calcium oxide. The unique firing process and the addition of bone charcoal eliminate the impurities in the china clay, and the bone china appears whiter, finer, more transparent, lighter, less flawed, and thinner than ordinary porcelain, visually having a special cleanliness Sensitive, and the strength is higher than that of ordinary porcelain, which is twice that of daily-use porcelain. [0003] High-quality animal ashes (mostly bovine bones) have been used as the main raw material in traditional bone china blanks. With the development of...
