use

Uses of zircon powder:

1. Used in casting coatings and ceramic cores in the investment casting (precision casting) industry.

2. Zirconium powder is used as the main material and glazed in the ceramic industry, so that the made ceramics increase wear resistance and surface finish.

3. Zirconium powder has special uses in many chemical industries, including cosmetics, cement, food preservative, leather, fiber (used to make flame retardant fibers).

4. The refractive index of zircon powder is high 1.93-2.01, chemical stability, is a high-quality, inexpensive emulsion, widely used in the production of various architectural ceramics, sanitary ceramics, daily ceramics, first-class handicraft ceramics, etc., in the processing and production of ceramic glazes, a wide range of use, large application. The reason why zircon powder is widely used in ceramic production is also because of its good chemical stability, so it is not affected by the ceramic firing atmosphere, and can significantly improve the billet glaze bonding performance of ceramics and improve the hardness of ceramic glaze. Zirconium powder has also been further used in the production of color picture tubes in the TV industry, emulsified glass and enamel glazes in the glass industry. The melting point of zircon powder is high: 2500 degrees Celsius, so it is also widely used in refractory materials, zirconium pounding materials, castables, and spray coatings.
