Problems solved by technology

In the prior art, the crystallite phase of glass-ceramic ceramics is generally CaSiO3 or Zn2SiO4, which has low transparency, single surface texture, and monotonous color; and generally one or more of TiO2, ZrSiO4, ZrO2 and P2O5 are used as crystals. Nucleating agent to promote the formation of crystal nuclei, but natural zircon has radiation hazards, lead has heavy metal pollution, and titanium ore is a harmful ion in ceramics, which is easy to cause ceramic spots, impregnation, etc., so it should be avoided. Nucleating agent

Abstract

The invention discloses a glass-ceramic ceramic tile, which comprises the following component raw materials in parts by weight: 10-25 parts of crystal frit, 10-20 parts of quartz, 5-10 parts of wollastonite, 10-30 parts of diopside, 5-10 parts of anorthite, 5-10 parts of fluorite, 0-1.5 parts of colored metal oxide powder, 0-5 parts of feldspar, 0-5 parts of clay, the powder blank is prepared first and then pressed into tablets , after the initial firing, then the initial polishing, then the re-calcination, and finally the post-processing to get the finished glass-ceramic tiles. The ceramic raw materials used in the present invention produce microcrystalline crystal phases of various oxides under high temperature conditions, avoid using titanium, zirconium or lead oxides as crystal nuclei, and have no radiation and lead hazards. Crystal glass tiles have the characteristics of strong surface compactness, high transparency, rich texture, good hardness and wear resistance, and the present invention uses fluorite as a flux and color aid to make ceramics not easy to fade.

Description

Technical field [0001] The present invention relates to the field of ceramic technology, in particular to a glass-ceramic tile and a preparation method thereof. Background [0002] Glass-ceramic ceramics, also known as machinable ceramics, are mica glass-ceramics with synthetic mica as the main crystal phase, which is a ceramic material that can be machined. Glass-ceramic ceramics have good processing performance, vacuum properties, electrical insulation characteristics and high temperature resistance, chemical corrosion resistance and other excellent properties. Glass-ceramic ceramics have high mechanical strength glass-ceramics, mechanically processable glass-ceramics, and bioactive glass-ceramics. In the prior art, the microcrystalline phase of glass-ceramic ceramics is generally CaSiO3 or Zn2SiO4, which has low transparency, single surface texture, monotonous color; and generally uses one or more of TiO2, ZrSiO4, ZrO2 and P2O5 as a crystal nucleant to promote the formation o...
