Alumina powder is an alpha phase, high purity aluminum oxide with excellent strength and hardness. It is widely used for electrical, thermal and biomedical applications.

A wide range of grades and chemistries are available in the market. Grades are based on the heat treatment applied, crystal size, soda content, and degree of thermal conversion to alpha phase.

Activated Alumina powder (also known as activated alumina ceramic, alumina-oxide-based ceramic or ceramics) is a form of alumina which has been subject to a controlled oxidation at 900 deg C. It is an effective and cost-effective material for the manufacturing of ceramic parts.

Calcined alumina powder is an alpha phase, high-purity aluminum oxide with excellent strength and hardness. This alumina is widely used for electrical, thermal and biomedical application such as high-temperature insulation, substrate for electronic components and medical implants.

It is a stable phase with excellent strength and hardness and good dimensional stability. It is used in a wide variety of plastics, rubber, ceramics, and refractory products for reinforcement toughening, in particular, significantly to improve the ceramic density, finish, thermal fatigue resistance, fracture toughness, creep resistance, and wear resistance.
