Problems solved by technology

[0003] The traditional glass-ceramic production mostly adopts the sintering process. The high energy consumption of the sintering process in the production of glass-ceramics has always been a key bottleneck restricting the rapid development and large-scale production of glass-ceramics.
[0004] At present, the glass-ceramic plate has the problem of single product color, and the coloring process of glass-ceramic is very different from the coloring of glass. The coloring of glass only needs to add colorants to ensure a suitable melting atmosphere for coloring. glass of different colors

Abstract

The invention discloses a coffee microcrystal glass plate and a production method thereof. The coffee microcrystal glass plate is prepared by the following steps of: mixing 11 to 13 parts of magnesite, 65 to 75 parts of granite, 14 to 17 parts of phosphate ore, 7 to 8 parts of heavy calcium and 2 to 4 parts of manganese ore; melting at 1,350 to 1,500 DEG C; clarifying and homogenizing at 1,400 to 1,450 DEG C; performing calendaring molding at the molding temperature of 1,150 to 1,270 DEG C to prepare a glass belt; performing annealing treatment; performing coring and crystallization; and polishing to obtain the coffee microcrystal glass plate. According to the production method of the coffee microcrystal glass plate, calcium-magnesium-aluminum-silicon serves as a main component and MnO2 serves as a coloring agent, so the problem of single color of microcrystal glass is solved; and the raw materials of the calcium-magnesium-aluminum-silicon in the formula are derived from natural minerals which are not purified and the chemical components are stable, so the raw materials are easily available and the cost is low.

Description

technical field [0001] The invention relates to a building material and a production method thereof, in particular to a brown glass-ceramic plate and a production method thereof. Background technique [0002] Glass-ceramic not only has the basic properties of glass, but also has the polycrystalline characteristics of ceramics. It combines the characteristics of glass and ceramics and becomes a unique new type of material. Because of its high mechanical strength, high hardness, good wear resistance, strong corrosion resistance, good chemical stability and thermal stability, and can adapt to harsh environments, it has developed rapidly in the world in recent years. [0003] The traditional glass-ceramic production mostly adopts the sintering process. The high energy consumption of the sintering process in the production of glass-ceramics has always been the key bottleneck restricting the rapid development and large-scale production of glass-ceramics. The sintering process pro...
