preparation example Construction

[0035] A preparation method of colored glass-ceramics, the raw materials are configured according to the requirements, the raw materials are passed into the melting part, mixed and then melted to form a molten glass liquid, and then the glass liquid is passed into the cooling part, homogenized, clarified, and air bubbles are discharged in the cooling part , and then discharge the molten glass to the forming part, anneal after forming, and finally make colored glass-ceramic, wherein the temperature in the forming part is kept at 1320 ° C to 1400 ° C, and the time for the glass liquid to be stored in the forming part is 1 to 10 hours. After cooling down, it is annealed after forming, and finally made into colored glass-ceramics. The heat preservation process of the forming part is conducive to the growth of crystal nuclei. Since the raw material may stick in the mold cavity during the crystallization process, the mold cavity needs to be destroyed, so the mold cavity can be made...

Abstract

The invention provides vanadium-pentoxide-containing colored microcrystalline glass. The microcrystalline glass comprises the following components by mass percentage: silicon, calcium, magnesium, aluminum, lithium, barium, aluminum phosphate, calcium fluoride, a cosolvent, rare-earth metals and a coloring agent, wherein the silicon, the calcium, the magnesium, the aluminum, the lithium and the barium are essential, and the aluminum phosphate and the calcium fluoride are used for improving light transmittance. The microcrystalline glass is brown in appearance and good in glossiness.

Description

technical field [0001] The present invention relates to glass-ceramics, in particular to colored glass-ceramics containing vanadium pentoxide. Background technique [0002] Glass-ceramic consists of a glass phase and a crystal phase, and its main components are the same as those of glass and ceramics. By adding components such as vanadium oxide, the glass-ceramics can be made into different colors and light transmittances to meet the needs of beautiful decoration. [0003] "Effects of Vanadium and Neodymium on the Crystallization and Coloring of Lithium Aluminum Silicon Glass-Ceramics" discloses the influence of pentavalent vanadium on the color of glass-ceramics. In order to further improve the color of the glass, other colorants can also be added. [0004] 201010184813.2 relates to neodymium-containing fuchsia glass-ceramics, which has high flexural strength, close to 120MPa, but slightly higher thermal expansion coefficient and unknown melt viscosity. [0005] 20131016...
