Problems solved by technology

However, compared with traditional high-temperature porcelain, bone china also has its disadvantages. First, the hardness of the glaze is relatively poor. When the product is used for a long time, the glaze is easy to scratch, and tea stains, stains, etc. will occur; the second is relatively thermal stability. Poor, the product is prone to bursting when used in sudden cooling and sudden heating

Abstract

The invention relates to a preparation method of reinforced bone china and a product prepared therefrom. According to the preparation method, a green body formula comprises the following components in percentage by weight: 15 to 20% of kaolin I, 15 to 20% of kaolin II, 10 to 15% of feldspar, 5 to 10% of quartz, 8 to 10% of kaolin III, 2 to 5% of kaolin IV, 35 to 40% of high calcium powder, and 5 to 10% of low-temperature cornish stone; a glaze formula comprises the following components in percentage by weight: 10 to 15% of kaolin I, 30 to 40% of feldspar, 5 to 10% of quartz, 8 to 13% of borax, 5 to 10% of zinc oxide, 10 to 15% of cornish stone, 3 to 6% of dolomite, 8 to 12% of calcite, and 5 to 8% of barium carbonate. The production method is scientific and reasonable, advanced in process technology, high in rate of finished products, and high in product quality, realizes firing at medium and low temperatures and has the advantages that a lot of gas and fuel is saved, the defect rate caused by the glaze firing at high temperature is greatly reduced, the production cost is remarkably reduced, and thus a wide market prospect is brought.

Description

technical field [0001] The invention belongs to the field of inorganic non-metallic materials (ceramics), and in particular relates to a preparation method of reinforced bone china and a product thereof. Background technique [0002] Bone china has been used by nobles in various countries for a long time, and it is currently recognized as a high-grade porcelain in the world. Because of its "thin as paper, transparent as a mirror, sound like a chime, and white as jade", the porcelain is fine and transparent, the shape is beautiful and elegant, the color surface is moist and bright, and the flower surface is colorful, which makes it white and luxurious. The shape of the porcelain has the dual value of use and art. In history, it is a treasure for the palace and aristocratic collections. It is a symbol of power and status. It is known as the "king of porcelain" and "green and healthy ceramics". Due to its high quality, high style and high grade, bone china has become the must-...
