Black glass-ceramic plate and production method thereof

Abstract

The invention discloses a black microcrystalline glass sheet material and a production method thereof. The black microcrystalline glass sheet material contains the following ingredients in parts by weight: 2-4 parts of Na2O, 7-10 parts of MgO, 8-11 parts of Al2O3, 60-70 parts of SiO2, 2-4 parts of P2O5, 3-4 parts of K2O, 4.5-6.5 parts of CaO and 5-10 parts of Fe2O3. The production method comprises the steps of mixing 14-18 parts by weight of magnesite, 65-78 parts by weight of granite, 2-6 parts by weight of calcium dihydrogen phosphate, 5-10 parts by weight of heavy calcium carbonate and 4-9 parts by weight of iron oxide red and then producing by adopting an all-electric melting calendering method. According to the black microcrystalline glass sheet material and the production method thereof, a formula for the black microcrystalline glass sheet material is provided, the production method of the black microcrystalline glass sheet material is obtained, and the situation that the existing microcrystalline glass sheet materials are single in color is broken through; granite is taken as a main raw material, magnesite supplies MgO, calcium dihydrogen phosphate supplies P2O5 and CaO, iron oxide red supplies Fe2O3, heavy calcium carbonate supplies CaO, the raw materials all can be purchased in the surrounding, chemical components are relatively stable, and the production cost is relatively low.

Description

technical field [0001] The invention relates to a building material and a production method thereof, in particular to a black 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. In particular, the "Twelfth Five-Year New Material Industry Development Plan" announced by the Ministry of Industry and Information Technology in January 2012 included rolled glass-ceramic in the list of inorganic non-metallic new materials that will be developed as a key development, and has a great impact on the d...

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, beige and brown glass-ceramic plates are produced by using the waste granite by the full electric fusion calendering process, but the beige and brown glass-ceramic plates are difficult to meet the market's demand for multi-variety and multi-color glass-ceramics. Therefore, it is necessary to continuously study the formula and production process of glass-ceramics of different colors
