Product Description
This product is a high-purity aluminum oxide micro-powder (Al₂O₃) with a purity of over 99.5%. The particle size can be customized within the range of 2-50μm, making it suitable for high-end industrial fields such as precision ceramics, refractory materials, catalyst supports, and polishing/grinding. Advanced hydrothermal synthesis or calcination processes are employed to ensure high chemical stability and uniform particle size, meeting the rigorous requirements of different industries.

 

Core Advantages
High purity (≥99.5%) - Low impurities (Na₂O≤0.05%), suitable for high-demand industrial scenarios
Customizable particle size (2-50μm) - Flexibly adapts to different application needs
Excellent thermal stability - Resistant to high temperatures up to 1,800°C, ideal for refractory materials
Good sintering performance - Promotes ceramic densification and improves product strength
Strong chemical inertness - Resistant to acid and alkali corrosion, extending material service life
