Problems solved by technology

Among them, carbon black is used for coloring, but the percentage of carbon black is less than 5%, so whether the color of the obtained black porcelain is pure remains to be investigated. In addition, it has high strength and low brittleness, and there is no data to support it.
The preparation method of this invention is relatively cumbersome, and the obtained black ceramic material is slightly rough in texture, which is not suitable for the preparation of handicrafts. It is mainly for the comprehensive utilization of two industrial wastes, mineral processing tailings and vanadium extraction tailings, to solve the pollution problem

Abstract

The invention particularly relates to a black ceramic product and a production method thereof and belongs to the technical field of ceramic products. The black ceramic product is prepared from components in parts by mass as follows: 100 parts of a mineral material, 20-30 parts of black clay, 12-15 parts of ceramic sand, 3-4 parts of water glass and 27-45 parts of black pigment. The mineral material comprises components in percentage by weight as follows: 57%-60% of kaolin, 25%-27% of high clay, 9%-12% of quartz and the balance of feldspar. The ceramic sand is waste ceramic piece powder which does not affect the color. The formula is reasonable, the preparation method is simple, and the obtained black ceramic product has pure color, good compactness, high strength and low brittleness and isnot prone to breakage.

Description

technical field [0001] The invention belongs to the technical field of ceramic products, and in particular relates to a black porcelain product and a manufacturing method thereof. Background technique [0002] Black porcelain, also known as Tianmu porcelain, is a porcelain with black high-temperature glaze. It is an ancient porcelain-making process, and it is one of the common glaze colors of common folk utensils. The existing black porcelain production process is generally to apply black glaze on the outside of the body, and the black glaze is mainly to increase the content of iron oxide, but the addition of iron oxide will have a certain adverse effect on the strength and other properties of the porcelain. There are also more or less deficiencies in other prior art. [0003] The application number is 201510963321.6, and the title is "a kind of black porcelain and its preparation method". In the invention, 20-30 parts of feldspar, 30-40 parts of quartz sand, 5-10 parts of ...
