Embodiment 1

[0041] According to Table 2, each component described in Example 1 was weighed, wherein the quartz sand was vein quartz.

[0042] The preparation method comprises the following steps:

[0043] (1) Drying, sieving, and mixing the iron tailings in sequence to obtain dry powder iron tailings with a water content of 0.5% and a particle size of 40 mesh;

[0044] (2) dry powdered iron tailings are mixed with other components according to the stated ratio;

[0045] (3) Put the mixture obtained above in a box-type high-temperature electric furnace, and melt it at a temperature of 1500° C. for 1 hour to obtain molten glass with a viscosity of 10 Pa.s;

[0046] (4) The molten glass is flowed into water, and the water is quenched to become glass pellets;

[0047] (5) Put the glass pellets into the mold for nucleation and crystallization molding, nucleate at 650°C for 0.8 hours, then raise the temperature to 1060°C at a rate of 4.7°C / min, and crystallize and shape at a pressure of 25Pa ...

Embodiment 2

[0049] According to Table 2, the components described in Example 2 were weighed, wherein the quartz sand included a mixture of 40% vein quartz and 60% quartzite.

[0050] The preparation method comprises the following steps:

[0051] (1) drying, sieving, and mixing the iron tailings successively to obtain dry powder iron tailings with a water content of 1% and a particle size of 80 mesh;

[0052] (2) dry powdered iron tailings are mixed with other components according to the stated ratio;

[0053] (3) Put the mixture obtained above in a box-type high-temperature electric furnace, and melt it at a temperature of 1510° C. for 2 hours to obtain molten glass with a viscosity of 10.5 Pa.s;

[0054](4) The molten glass is flowed into water, and the water is quenched to become glass pellets;

[0055] (5) Put the glass pellets into the mold for nucleation and crystallization molding, nucleate at 650°C for 1 hour, then raise the temperature to 1040°C at a rate of 4.7°C / min, and cryst...

Embodiment 3

[0057] According to Table 2, each component described in Example 3 was weighed, wherein the quartz sand was opal.

[0058] The preparation method comprises the following steps:

[0059] (1) drying, sieving, and mixing the iron tailings successively to obtain dry powder iron tailings with a water content of 3% and a particle size of 120 mesh;

[0060] (2) dry powdered iron tailings are mixed with other components according to the stated ratio;

[0061] (3) Put the mixture obtained above in a box-type high-temperature electric furnace, and melt it at a temperature of 1520° C. for 2.5 hours to obtain molten glass with a viscosity of 11 Pa.s;

[0062] (4) The molten glass is flowed into water, and the water is quenched to become glass pellets;

[0063] (5) Put the glass pellets into the mold for nucleation and crystallization molding, nucleate at 650°C for 0.9 hours, then raise the temperature to 1020°C at a rate of 4.7°C / min, and crystallize and shape at a pressure of 25Pa , t...

Abstract

The invention discloses blue glass ceramics and a preparation method thereof, and aims to solve the problems of single color and high production process cost of the conventional glass ceramics. The blue glass ceramics are prepared from the following components in part by weight which serve as raw materials: 30 to 55 parts of iron tailings, 20 to 450 parts of quartz sand, 10 to 30 parts of lithium feldspar, 2 to 6 parts of soda ash, 2 to 6 parts of zinc oxide, 2 to 6 parts of barium carbonate, 0 to 1 part of manganese dioxide, 0 to 0.4 part of cobalt oxide and 0 to 3 parts of sodium nitrate. The invention makes waste profitable by using the iron tailings which are wastes as the raw material of the blue glass ceramics, can reduce pollution and protect environment, improve physiochemical performance of the product, solve the problem of single color of the glass ceramics, lighten corrosion of glass metal to a refractory material of a glass furnace and prolong service life of equipment. The blue glass ceramics of the invention have wide application.

Description

technical field [0001] The invention belongs to the field of glass, in particular to a blue glass-ceramic. The invention also relates to a preparation method of the blue glass-ceramics. Background technique [0002] Glass-ceramic is a polycrystalline material obtained by controlling the crystallization of glass. As a new type of material, glass-ceramic has a wider range of applications. Glass-ceramic plate is one of many varieties of glass-ceramics. It is a new type of high-grade building decoration material with high strength, wear resistance, corrosion resistance, weathering resistance, non-absorbent, easy to clean and maintain, and no radioactive hazards. Features and excellent appearance characteristics such as uniform color tone, soft and crystal-clear luster, dense and flawless surface. Because the properties of the glass-ceramic plate are superior to natural stone in all aspects, it has been widely used in high-end decoration projects such as interior and exterior ...
