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 655°C for 0.8 hours, then raise the temperature to 1020°C at a rate of 4.9°C / min, and crystallize and shape under the condition of...

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 655°C for 1 hour, then raise the temperature to 1030°C at a rate of 4.9°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 1480° 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 655°C for 0.9 hours, then raise the temperature to 1050°C at a rate of 4.9°C / min, and crystallize and shape at a pressure of 25Pa , th...

Abstract

The invention discloses a black glass ceramic and a production method thereof in order to solve the problems of the conventional glass ceramic, i.e. single color and high production technique cost. The black glass ceramic is produced with the following components in part by weight: 25 to 50 parts of iron tailings, 20 to 50 parts of quartz sand, 10 to 32 parts of petalite, 2 to 6 parts of sodium carbonate, 2 to 6 parts of zinc oxide, 2 to 6 parts of barium carbonate, 0 to 0.1 part of copper oxide, 0 to 2 parts of manganese dioxide, 0 to 0.2 part of cobalt oxide, 0 to 2 parts of chromic oxide and 0 to 3 parts of sodium nitrate. Since the invention utilizes the discarded iron tailings as the material of the black glass ceramic, the waste is made profitable, pollution is reduced, the environment is protected, moreover, the physicochemical performance of the product can be enhanced, and the single-color problem of the black glass ceramic is solved; the corrosion of the refractory material of a glass furnace by molten glass is reduced, and thereby the service life of the equipment is prolonged; and the application range of the black glass ceramic is wide.

Description

technical field [0001] The invention belongs to the field of glass, in particular to a black glass-ceramic. The invention also relates to a preparation method of the black 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 exterio...
