Production information:
Calcined alumina powder was made from industrial Al(OH)3 or Al2O3, under the suitable temperature calcined to be -Al2O3, then grind in mill to be the alumina powder. This high temperature calcined alumina powder have very high melting point, excellent mechanical strength, high hardness, high specific resistance and good thermal conductivity.
Application:
• High temperature refractories
• Castable
• Electric porcelain device
• Automobile spark plug
• High alumina porcelain parts
• Wear-resistant Porcelain Parts
• Good for electronic substrate
• Abrasive material
• Polishing material
• High alumina structural ceramic
• Various abrasives ,abrasive tools and fillers
• Fine powder of various ceramic and refractory grade alumina
