  • The firing steps of alumina ceramics

    The firing steps of alumina ceramics typically involve shaping the raw material into the desired form, such as through pressing or slip casting, followed by drying to remove moisture. Then, the shaped alumina is fired in a kiln at high temperatures, usually between 1300°C to 1700°C, to sinter the particles and create a dense ceramic structure. Cooling and finishing processes may follow to achieve the final properties and dimensions required for the specific application.

    How is the strength of alumina ceramics?

    Alumina ceramic, also known as high-purity alumina, is exceptionally strong and has excellent mechanical properties. Its strength can be attributed to several factors: ​1.Hardness: Alumina ceramics are extremely hard, ranking high on the Mohs scale of mineral hardness. This hardness contributes to their strength and resistance to wear and abrasion. 2.Stiffness: Alumina ceramics have high stiffness and are rigid materials, which enhances their strength and ability to withstand mechanical stresses without deforming.
