Product Description

White corundum Micro Powder

White corundum is widely used in ceramic glazes due to its high hardness, chemical stability and excellent sintering performance, which can significantly improve the quality of glaze and product performance. The following are its main advantages:
1. Improve glaze hardness and wear resistance
The Mohs hardness reaches 9, which is much higher than ordinary glazes (usually 5-6), making the ceramic surface more scratch-resistant and suitable for daily-use porcelain with high-frequency contact (such as tableware and bathroom ceramics).
The wear resistance is enhanced, extending the service life of the glaze and reducing the wear and gloss loss caused by long-term use.
2. Optimize the gloss and texture of the glaze
The high-purity white corundum particles are uniform, and the glaze is denser after firing, reducing pores and defects (such as pinholes and orange peel).
The particle size can be adjusted (usually 1-10μm) to achieve matte, semi-gloss or high-gloss effects to meet different decoration needs.
3. Enhance chemical stability
Acid and alkali corrosion resistance, suitable for chemical ceramics or outdoor architectural ceramics (such as acid-resistant bricks, exterior wall glazed tiles).
Reduce discoloration or peeling of the glaze due to environmental erosion.
4. Improve high temperature performance
The melting point is as high as 2050℃, which remains stable during the glaze firing process to avoid high temperature volatilization or decomposition.
Low thermal expansion coefficient, better matching with the body, reducing the risk of glaze cracking.

Application

1. Precision grinding and polishing
Due to its high hardness and uniform particle size, white corundum micro powder is widely used in high-precision grinding and polishing of precision optical components (such as lenses, prisms), semiconductor wafers, precision metal parts, etc., and can achieve the stringent requirements of surface finish and dimensional accuracy.
2. Advanced ceramic and refractory additives
In the preparation of special ceramics or refractory materials, white corundum micro powder can be used as a reinforcing phase to improve the material's high temperature resistance, thermal shock resistance and mechanical strength, such as for the manufacture of high-temperature kiln linings, spacecraft insulation components or high-performance ceramic tools.
3. Surface treatment and functional coatings
Used for sandblasting (micron-level cleaning or roughening) of metal or composite surfaces, or as a raw material for thermal spray coatings, giving the substrate wear resistance, corrosion resistance and insulation properties, commonly used in industrial fields such as mechanical parts and turbine blades.

4. For the use of wear-resistant floor.

5. Production of Polishing Compound, Metal Polishing compound and Polishing Compound liquid.

6. Production of making Oilstones, Grinding wheels, Sandpaper, Sanding belt, Mounted Wheels.
