Embodiment 1～7

[0020] In this embodiment, the following method is adopted to prepare high alumina glass material:

[0021] (1) Prepare glass batch according to the components described in Table 1 below;

[0022] (2) The glass batch material is melted into molten glass in a high-temperature furnace with an oxidizing atmosphere, and the melting temperature is 1650°C;

[0023] (3) Pour the molten glass into the mold for rapid cooling, then anneal it, keep it warm for 3 hours and then cool it in the furnace.

[0024] Table 1 Example 1 ~ 7 glass batch composition and ratio

Abstract

The invention relates to opacified peacock green high-alumina glass which is composed of a high-alumina glass base material and a coloring material; the coloring material is composed of Cr2O3, NiO andCoO; the mass percentages of the Cr2O3, NiO and CoO in the total chemical composition of the glass are 0.8-3%, 0.2-0.5% and 0.1-0.3% respectively. According to the opacified peacock green high-alumina glass and the preparation method thereof of the invention, the traditional colorants Cr2O3, NiO and CoO are used for coloring the high-alumina glass system; through proportion design, the colorantscan achieve neutralization to obtain a whollyopacified peacock green effect with liquid flow patterns without destroying good mechanical properties of the high-alumina glass; and the preparation method has the advantages of simple preparation process, low cost and uniform and stable coloring.

Description

technical field [0001] The invention relates to a preparation method of colored high-alumina glass, belonging to the technical field of glass manufacturing. Background technique [0002] Colored glass refers to glass that can absorb, reflect, and pass through different wavelengths of light to present different colors. Traditional colored glass is based on the soda-lime-silica glass system, which has a low melting temperature and poor strength and impact resistance. High alumina glass has better mechanical properties than traditional soda lime silica glass because of its denser glass network structure. In the industrial method of preparing colored glass, there is a layer of organic material color layer sprayed on the glass surface, but the coating will age or even fall off with time, and the coloring effect will naturally deteriorate. With the development of social economy, people are more and more interested in personalized products. The color glass based on glass matrix ...
