Alumina ceramic
99.3% alumina ceramic, also known as high-purity alumina, is exceptionally strong and has excellent mechanical properties. Its strength can be attributed to several factors:
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.
Stiffness: Alumina ceramics have high stiffness and are rigid materials, which enhances their strength and ability to withstand mechanical stresses without deforming.
High Temperature Resistance: They can withstand high temperatures without losing their mechanical properties, making them suitable for use in high-temperature environments where other materials would fail.
Chemical Resistance: Alumina ceramics are highly resistant to chemicals, acids, and alkalis, which adds to their durability and strength in harsh operating conditions.
Electrical Insulation: They exhibit excellent electrical insulation properties, making them ideal for applications requiring electrical insulation combined with mechanical strength.
Low Thermal Expansion: Alumina ceramics have a low coefficient of thermal expansion, meaning they do not expand or contract significantly with temperature changes. This property contributes to their dimensional stability and strength in varying thermal conditions.
Corrosion Resistance: They are resistant to corrosion, rust, and oxidation, which further enhances their longevity and strength in corrosive environments.
Overall, 99.3% alumina ceramic is known for its exceptional strength, hardness, stiffness, and resistance to various environmental factors, making it a preferred choice for demanding applications in industries such as aerospace, automotive, electronics, and medical equipment manufacturing.
Application of industrial ceramic pipes
1. Industrial ceramic pipesare used as support tubes for high-temperature kilns.
