Problems solved by technology

[0003] A major feature of architectural glass-ceramics as a decorative material is that the color can be designed and the color is soft. At present, the colored glass-ceramics on the market are mainly sintered, but they have the disadvantages of high porosity, high energy consumption, and low output.
However, glass-ceramics suitable for other industrial productions have a relatively single color, and when producing colored glass-ceramics, there are disadvantages of high refueling costs and low efficiency in the furnace.

Abstract

Cinerous glass ceramic belongs to the technical field of glass ceramics and comprises the following raw materials by weight percent: 32-44% of SiO2, 28-38% of Al2O3, 7.2-15.6% of CaO, 6-13% of MgO, 6-13% of Na2O and/or K2O, 0-2% of ZnO, 5-13% of TiO2 or TiO2+ZrO2, and a colorant, wherein the colorant is 2-2.5% of CeO2 or a mixture of 1.2-2% of CeO2 and 0.05-0.2% of Fe2O3. The invention also discloses a preparation method and application of cinerous glass ceramic. The cinerous glass ceramic does not contain fluorides, is soft in color, and has the color approximate to that of natural cinerous granite and the physical and chemical properties superior to that of natural granite.

Description

technical field [0001] The invention belongs to the technical field of glass-ceramics and relates to a blue-gray glass-ceramic, in particular to a blue-gray glass-ceramic and its preparation method and application. The blue-gray glass-ceramics of the invention does not contain fluoride and has a soft color , the color is similar to natural blue-gray granite, and its physical and chemical properties are better than natural granite. Background technique [0002] Glass-ceramic is a material containing glass phase and microcrystalline phase obtained by controlling the heat treatment system of the base glass of a specific composition. By controlling the basic composition and heat treatment system, glass-ceramics with different properties can be obtained, which can be widely used in various fields. Architectural glass-ceramic has the characteristics of wide source of production raw materials, soft and uniform color, bright color, no radiation, zero porosity and excellent physical...
