Abstract

The invention discloses a super-flat glaze frit and a method of manufacturing super spar from the same. The super-flat glaze frit can allow glazes to have good viscosity and fluidity at high temperature. The frit and a raw material are used in match according to a mass ratio of (50-100):100. The super-flat glaze frit plays a large role in glazes to allow flatter glaze surfaces with high hardness and good transparency after firing. The frit has a high beginning melting point so as to avoid generation of gas bubbles. The cost of the super-flat glaze frit is 25% of the cost of one-firing minicrystal frit dry particles, thus greatly saving the cost.

Description

Technical field [0001] The present invention involves a method of super flat glaze melting and prepared by it. Background technique [0002] With the increasingly enrichment of material and culture, people have put forward higher requirements for tiles.Due to the luxurious decorative effect, the bright and flat glaze has always been a more preferred decorative material for consumers, and it is also a popular research topic in the ceramic industry.Due to the limitations of production technology technology, ceramic glazes are not pure, and their surfaces are more or less slightly uneven.The surface of the surface is smooth and flat, and the transparent glaze has not been able to make a breakthrough in technical. Invention content [0003] One of the purpose of the present invention is to provide an ultra -flat glaze melting block with a lower melting point with a higher melting point. [0004] Another purpose of the present invention is to provide an ultra -flat glaze containing t...
