example 1

[0025] In parts by weight, weigh 1 part of aluminum nitrate nonahydrate crystals, 3 parts of ammonium bicarbonate powder and 40 parts of deionized water into a beaker, mix at a speed of 300r / min for 15min, and obtain a mixed solution after stirring. Put the liquid into the separatory funnel, pour 5 times the mass of the mixed solution into the flask into a 25% ammonium bicarbonate solution, open the separatory funnel, drop the mixed solution in the separatory funnel into the flask, and add 10mL / After the titration, the reaction solid was obtained by suction filtration, and the reaction solid was washed with absolute ethanol and distilled water for 3 times. After washing, it was placed in a muffle furnace, heated to 105°C, dried for 6 hours, and then heated up after drying. to 500°C, calcined at high temperature for 30 minutes to obtain the reaction product, put the reaction product into a pulverizer to pulverize, pass through a 400-mesh sieve to obtain the ground product, and ...

Abstract

The invention relates to a preparation method of a thermostable and high-toughness ceramic glaze and belongs to the technical field of ceramic glaze preparation. The preparation method includes: usingaluminum nitrate nonahydrate crystals and ammonium bicarbonate as the raw materials to prepare a grinding product, using sodium silicate and ammonia water as the raw materials to prepare a calciningproduct, mixing the calcining product and the grinding product with other stone materials, crushing the mixture, subjecting the crushed mixture to high-temperature melting, coating a green body with the molten mixture, and naturally cooling to obtain the thermostable and high-toughness ceramic glaze. The preparation method has the advantages that specific surface area can be increased by preparingan aluminum oxide ceramic glaze into a nano material, nano aluminum oxide is evenly dispersed on the surface of a ceramic glaze interface and can increase the overall thermostability and mechanical performance of the ceramic glaze, a nano-silica material prepared by the sodium silicate is introduced into the ceramic glaze and can increase the toughness and thermostability of the ceramic glaze, and the prepared ceramic glaze is promising in application prospect.

Description

technical field [0001] The invention relates to a preparation method of thermally stable and high-toughness ceramic glaze, which belongs to the technical field of ceramic glaze preparation. Background technique [0002] In China's splendid artistic culture for thousands of years, ceramic art has always occupied a relatively important position. Ceramic products have become the object of choice for customers due to their advantages such as high density, good thermal stability, small shrinkage deformation, easy washing and keeping clean, stable chemical properties, and durability, and have a broad market. For ceramic products, the glaze is an extremely critical part. As we all know, glazes can improve the surface properties of ceramic products. Most glazes can make the products smooth, bright and non-absorbent. It is also beneficial to increase the strength of the products and improve the thermal and chemical stability of the products. [0003] Generally speaking, the so-call...
