Spherical Alumina Powder (Conventional Type) is produced by the high-temperature melting-sphere-jet method, and then sieving, purification, and other processes to produce the final object.
Product Name: Spherical Alumina Powder
Material Type: α-Al₂O₃ (Alpha Alumina)
Morphology: Spherical (spheroidized)
Al₂O₃ Content:≥ 99.5%(Available grades up to 99.99%)
SiO₂:≤ 0.03%
Fe₂O₃:≤ 0.01%
Na₂O:≤ 0.2%
SPHERICAL ALUMINA POWDER ADVANTAGES
Perfect Spherical Shape: Improves flowability and dispersibility in resin systems
High Thermal Conductivity: Typically 20–30 W/m·K (depending on formulation)
High Chemical Purity: Stable under harsh processing conditions
Excellent Insulation: Electrically insulating yet thermally conductive
Low Oil Absorption: Allows high loading in polymer matrices without excessive viscosity
Uniform Particle Size: Reduces agglomeration and enhances composite performance
