Colored high-transparency melt block and method for preparing same

Abstract

The invention discloses a colored high-transparency melt block and a method for preparing the same. The colored high-transparency melt block comprises main chemical compositions including 10-20 parts of Al2O3, 40-50 parts of SiO2, 0.05-0.10 part of Fe2O3, 10-15 parts of CaO, 5-10 parts of MgO, 1-3 parts of K2O, 0.5-2.0 parts of Na2O, 0.01-0.05 part of TiO2, lower than 0.01 part of SrO, 0.1-1.0 part of Li2O, lower than 0.01 part of PbO, 0.001-0.005 part of ZnO, 1-5 parts of B2O3, 0.10-0.50 part of P2O5, 2-6 parts of BaO, 0.010-0.050 part of SO3, 3-7 parts of ZrO2, 0.50-1.00 part of CeO2 and 1-5 parts of F. The ignition loss of the colored high-transparency melt block is 3-5%. The colored high-transparency melt block and the method have the advantages that the colored high-transparency melt block can be closely bonded with sintered ceramic substrates without separation or layering; expansion coefficients of the colored high-transparency melt block and blanks are matched with one another, and accordingly sintered products have flat surfaces; the surfaces of the sintered products are free of bubbles and pinholes, and the sintered products are good in glossiness and high in transparency.

Description

Technical field [0001] The invention belongs to the field of ceramics, and specifically relates to a colored and highly transparent frit and a preparation method thereof. Background technique [0002] At present, the surface of the glass-ceramic composite plate on the market adopts a translucent or opaque opalescent crystallite layer, and its surface decoration effect is completely dependent on different colors of glass-ceramic frit and its crystallizing texture, and the manufacturing cost is high. , The transparency is not good, the color and texture are relatively simple and not rich enough. In order to achieve a certain decorative effect, some companies even directly use glass phase as a method to achieve three-dimensional colors, but its physical and chemical properties are very different from those of glass-ceramics, the texture is not clear, and the three-dimensional sense is not strong. Summary of the invention [0003] In order to overcome the shortcomings of the prior ar...

[0002] At present, the surface of glass-ceramic composite plates on the market adopts translucent or opaque opaque microcrystalline layer, and its surface decoration effect is completely dependent on different colored glass-ceramic frits and their crystallization textures, and the manufacturing cost is high. , the transparency is not good, the color and texture are relatively simple and not rich enough

In order to achieve a certain decorative effect, some enterprises even directly use the glass phase as a method to achieve three-dimensional color, but its physical and chemical properties are very different from those of glass-ceramics, the texture is not clear, and the three-dimensional effect is not strong
