Problems solved by technology

The existing black porcelain production process is to apply black glaze on the outside, and the inside of the porcelain itself is not necessarily black. Once there are cracks or gaps, the internal color will be exposed. For carving crafts It is not easy to use, and the black glaze in the prior art mainly relies on increasing the content of iron oxide, and then iron oxide has certain adverse effects on the strength and hardness of porcelain
Moreover, the porcelain produced by the existing technology is very brittle and very easy to crack

Abstract

The invention relates to black ceramic and a preparation method thereof, and relates to the technical field of ceramics. The black ceramic is prepared from the raw material components of, by weight, 20-30 parts of feldspar, 30-40 parts if quartz sand, 5-10 parts of talc, 5-8 parts of kaolin, 10-20 parts of Laiyang clay, 5-10 parts of flint clay, 8-16 parts of pyrophyllite, 3-7 parts of aluminum silicate, 2-4 parts of carbon black, 1-3 parts of calcium carbide and 4-6 parts of potassium manganite. The method comprises the following steps: slurry preparation is carried out, wherein the raw materials are blended according to the formula; and ball milling, sieving, iron removing and pond storage steps are carried out, such that a slurry is obtained; a mold is prepared; cast molding is carried out, wherein grouting and blowing are carried out with a plaster mold; demolding is carried out; and blank trimming is carried out, such that a semi-finished product blank is produced; and sintering is carried out, wherein a spray-glazed semi-finished product is subjected to high-temperature firing in a kiln, such that a product is obtained, wherein the sintering time is 17-20h, and a sintering temperature is 1210-1290 DEG C; and examination is carried out. The black ceramic has the advantages of high strength, low brittleness, cracking resistance, easy carving, and pure color. According to the preparation method, glaze spraying is not needed.

Description

Technical field: [0001] The invention relates to the technical field of ceramics, in particular to black porcelain and a preparation method thereof. Background technique: [0002] Porcelain is the general term for pottery, stoneware and porcelain. Any utensils made of two different types of clay, pottery clay and porcelain clay, as raw materials, through batching, molding, drying, roasting and other processes can be called ceramics. Black porcelain Black porcelain is also called Tianmu porcelain. It is an ancient Chinese porcelain making craft. It is one of the common glaze colors of common folk utensils. Porcelain with black high temperature glaze. Black porcelain is developed on the basis of celadon. The existing black porcelain production process is to apply black glaze on the outside, and the inside of the porcelain itself is not necessarily black. Once there are cracks or gaps, the internal color will be exposed. For carving crafts It is not easy to use, and the b...
