Problems solved by technology

However, this method has the following technical defects: when the green body is close to the lowest eutectic point, there is no liquid phase formation, but once it reaches the lowest eutectic point temperature, a large amount of liquid phase suddenly appears, and the amount of liquid phase increases rapidly with the increase of temperature. resulting in rapid deformation of the porcelain body
Therefore, this method in the prior art reduces the sintering temperature while also shortening the firing temperature range. Usually, the firing temperature range is very narrow and only about 30°C. The product is easily deformed and brittle, so it is difficult to ensure that the product is various performance indicators

Abstract

The invention discloses ultra-low temperature sintered ceramic tiles and a preparation method thereof. The green tiles have a composite solvent system, so eutectic point is improved; the advanced sintering and gradual occurrence of a liquid phase with high viscosity in areas at different sintering temperatures reduce the sintering temperature greatly and enlarges the range of the sintering temperature of the green tiles; and thus, the performance indexes of the product are guaranteed. The preparation method of the invention fulfills the aim of energy conservation and consumption reduction, greatly reduces the emission of CO2 waste gas, can create economic and social benefit, has a great significance for protecting natural environment and contributes to the sustained development of industrial production.

Description

technical field [0001] The invention relates to the technical field of architectural ceramics, in particular to an ultra-low temperature sintered ceramic tile and a preparation method thereof. Background technique [0002] The annual output of my country's architectural ceramic products is about 3 billion square meters. Calculated by the weight of 20-24 kg per square meter, the annual consumption of mud and ore materials is 60-72 million tons. Based on the fuel consumption of 1.4 to 1.5 liters per square meter of product, the annual fuel consumption will reach 420 to 450 million liters. Ceramic tiles (such as vitrified tiles) are one of the main products of architectural ceramics. Because of their high strength, corrosion resistance, and generous appearance, they are widely used in household, living, entertainment and other fields. At present, the production and preparation of this type of ceramic tile is usually carried out at a firing temperature of 1150-1220° C., and the...
