Problems solved by technology

At present, research and development of products to replace zirconium silicate mainly focus on phosphorus-zirconium system, phosphorus-zirconium-boron composite system, zirconium silicate nano-system and titanium white glaze system. When these systems are used, the ceramic firing process is very high, so App is restricted

Abstract

The invention discloses a ceramic whitening agent. The ceramic whitening agent is characterized by comprises the following substances in parts by weight: 51-66 parts of zirconium silicate, 31-40 parts of feldspar, 2-3 parts of calcite, 10-18 parts of talc, 4-5 parts of zinc oxide, 4-6 parts of barium carbon, 0-5 parts of quartz powder, 0-5 parts of raw kaolin, 0-5parts of calcined kaolin, 50-99.5 parts of hydrated aluminum hydroxide, 15-40 parts of activated silicon micropowder, 3-5 parts of zirconium boride, 1.5-3.6 parts of nickel oxide, 1.5-2.8 parts of magnesium olivine and 0.6-4.8 parts of sodium carbonate serving as a mineralizer. The invention has the beneficial effects that the costs of ceramic enterprises are reduced, the limited zircon sand resource is saved and the radioactive contamination of the ceramic is reduced.

Description

technical field [0001] The invention relates to a ceramic whitening agent. Background technique [0002] Zirconium silicate, as a high-quality and cheap whitening agent and opacifying agent in the ceramic industry, is widely used at home and abroad. Due to the limited storage of zircon sand, the raw material of zirconium silicate, the price keeps rising, which leads to the increase in the cost of ceramic enterprises. At the same time, zirconium silicate contains certain radionuclides radium, thorium, uranium and potassium-40, which increases the radioactivity of ceramic products. At present, research and development of products to replace zirconium silicate mainly focus on phosphorus-zirconium system, phosphorus-zirconium-boron composite system, zirconium silicate nano-system and titanium white glaze system. When these systems are used, the ceramic firing process is very high, so Application is limited. Contents of the invention [0003] The technical problem to be solve...
