Problems solved by technology

[0004] The existing black glass-ceramic colorant is generally composed of iron oxide and manganese dioxide. This black glass-ceramic colorant will change color during the secondary color development process, which directly leads to the black color of the black glass-ceramic, which is difficult to obtain. Meet the requirements

Abstract

The invention provides a black microcrystalline glass color agent and black microcrystalline glass, wherein the black microcrystalline glass color agent comprises ferric oxide, nickel oxide, cobalt oxide and chromic oxide, wherein the mass ratio of ferric oxide to nickel oxide to cobalt oxide to chromic oxide is (2-5):(0.4-0.8):(0.05-0.1):(0.001-0.004). The black microcrystalline glass color agent provided by the invention is stable in performance and does not change color in the secondary developing process, so that black pure microcrystalline glass can be obtained.

Description

technical field [0001] The invention relates to the field of glass-ceramics, in particular to a black glass-ceramic colorant and black glass-ceramics. Background technique [0002] With the steady and continuous development of my country's national economy, people's living standards are improving, and the demand for high-grade building materials is increasing, especially the demand for alternative products of non-radiation high-grade stone is more urgent, but domestic high-grade stone substitute products are brittle. It is not easy to process and shape, so many high-grade stone materials need to be imported from abroad, and the cost is greatly increased. [0003] Glass-ceramics, also known as ceramic glass, has dual characteristics of glass and ceramics. Glass-ceramics is composed of crystals with regular atomic arrangements. Therefore, glass-ceramics has higher brightness than ceramics and stronger toughness than glass. Glass-ceramic combines the triple advantages of glass,...
