Abstract

The invention discloses black glass ceramic and a preparation method thereof. The ceramic is prepared from, by weight, 50-70 parts of mica powder, 12-25 parts of potassium permanganate, 5-16 parts of mica powder, 6-12 parts of blue vitriol, 4-14 parts of sodium silicate, 16-28 parts of silicon dioxide, 10-40 parts of zinc oxide and 3-10 parts of ammonium polyacrylate. The preparation method of the black glass ceramic comprises the steps of weighing raw materials according to the parts by weight, mixing and adding the raw materials into a crucible, heating the crucible, keeping temperature retention for 1-2 hours within the range from 1500 DEG C to 1600 DEG C, conducting shocking chilling, forming frit, smashing the frit into glass powder, placing the glass powder into a crucible at the temperature ranging from 1050 DEG C to 1100 DEG C for fusion, conducting natural cooling, and obtaining the black glass ceramic. According to the formula of the black glass ceramic, the mixing is conducted according to a certain proportion, then the black glass ceramic is obtained and is in black, products obtained after the mixing are stable in color and luster, little pollution is caused in the production process, only traditional ceramic firing equipment is needed for production, no additional dedicated electroplating equipment is needed, and the cost is saved.

Description

technical field [0001] The invention belongs to the field of glass ceramic materials, and in particular relates to a black glass ceramic and a preparation method thereof. Background technique [0002] Glass-ceramics, also known as glass-ceramic, is a kind of composite material combined with crystal phase and glass made through high-temperature melting, molding, and heat treatment. With high mechanical strength, adjustable thermal expansion, thermal shock resistance, chemical corrosion resistance, low dielectric loss and other superior properties, it is widely used in machinery manufacturing, optics, electronics and microelectronics, aerospace, chemistry, industry, biomedicine and construction and other fields. Due to the complex manufacturing process and high technical requirements of glass ceramic panels, the high-quality glass ceramic production process and control technology are basically monopolized by foreign countries, and the domestic glass ceramic production process...
