Preparation method of glossy transparent ultra-low-temperature glaze powder material

Abstract

The invention discloses a preparation method of a glossy transparent ultra-low-temperature glaze powder material. The method comprises the following steps of (1) using a precision electronic balance for weighing 0-34.4 g of B2O3, 25.14-50 g of SiO2, 5-9.94 g of Al2O3, 3.81-7.58 g of CaO, 11.74-23.35 g of ZnO, 2.16-4.3 g of K2O, 1.57-16.11 g of Na2O, 1.04-2.07 g of BaO, 0.6-1.19 g of MgO, 48 g of borax, 1-1.2 g of SrO, 2.1-3.5 g of ball clay, 1.31-2.55 g of Li2O and 0.51-2.11 g of Na5P3O10 which are adopted as raw materials; (2) grinding the raw materials into 300 mesh sieve fineness through aball mill to form glaze powder at a working speed of 25 rad / min and then obtaining the ultra-low-temperature glaze powder material. The preparation method of the glossy transparent ultra-low-temperature glaze powder material utilizes the novel low-temperature fast-burning raw materials as fluxing agents for introducing alkali metal oxides or alkaline earth metal oxides, and since the raw materialsare characterized by completing a physicochemical reaction at a lower temperature, by utilizing this characteristic of the raw materials, low-temperature ceramic glaze is prepared, so that the purpose of fast burning at the low temperature is achieved. Moreover, the raw materials have few harmful impurities, less ignition loss, high melting performance and low viscosity at the high temperature, and a flat and smooth glaze surface is easily formed.

Problems solved by technology

Existing low-temperature glazes generally contain frit, refractory components such as alumina and silicon oxide, and some strong fluxes such as lead oxide. However, the production cost of frit glaze is high and requires secondary firing. In addition, although lead can greatly reduce the firing temperature of the glaze, its toxicity limits its use in daily-use ceramics. range of applications, and is likely to cause environmental pollution
