Description

Alumina ceramic balls are made by isostatic press and sintered at high temperature by micro fine Al₂O₃ powder. The small crystal size is free from air pockets and has better wear resistance. It is ideal media for larger ball mills.

Features:
  • More economic than zirconia ball
  • Higher density than glass or agate ball
  • Lower contamination than glass ball

Frequently Asked Questions

Q What are alumina ceramic balls made of?
Alumina ceramic balls are manufactured using micro fine Al₂O₃ (aluminum oxide) powder through an isostatic pressing process and then sintered at high temperatures. This process results in a dense, fine-crystal structure with minimal air pockets and excellent wear resistance.
Q What industries use alumina ceramic balls?
Alumina ceramic balls are widely used across multiple industries including mining and mineral processing, ceramics, paints and coatings, electronics, petrochemicals, and pharmaceutical manufacturing. They are valued for their hardness, chemical inertness, and low contamination properties.
Q How do alumina ceramic balls compare to zirconia balls?
Alumina ceramic balls are more cost-effective than zirconia balls while still offering excellent wear resistance and low contamination. They also have a higher density than glass or agate balls, making them a preferred choice for applications where budget and performance need to be balanced.
Q Can alumina ceramic balls be used as catalyst supports?
Yes. Alumina ceramic balls are widely used as inert catalyst carrier balls in petrochemical, chemical, and refinery fixed-bed reactors. Their excellent thermal stability, mechanical strength, and chemical inertness make them ideal for these demanding applications.
Q Are alumina ceramic balls suitable for pharmaceutical applications?
Yes. Alumina ceramic balls are suitable for pharmaceutical applications due to their high purity, corrosion resistance, and low contamination characteristics. They can be used as filling media in reactors and columns, as well as for fine grinding of pharmaceutical ingredients.
Q What sizes and grades of alumina ceramic balls are available?
