Alumina ceramic wear tiles are high-performance industrial components made primarily from aluminum oxide (Al₂O₃). By changed the alumina content (typically from 85% to 99.9+%), that can tailor their properties for specific demands of wear, corrosion, temperature, and electrical insulation.
Key Properties and Characteristics of alumina ceramic tile:
-
Extreme Hardness & Wear Resistance: Second only to diamonds and a few other ceramics (like silicon carbide) in hardness, they offer outstanding resistance to abrasion, sliding wear, and particle erosion.
-
High Compressive Strength: They can withstand immense crushing loads, that making them suitable for heavy machinery and load-bearing linings.
-
Excellent Chemical Inertness: Highly resistant to corrosion from acids, alkalis, and solvents (except for hydrofluoric acid and strong alkalis at high temperatures). They do not rust or degrade chemically.
-
High-Temperature Stability: They maintain origin shape and strength even temperatures up to 1600°C (2900°F), with excellent thermal shock resistance depending on the grade.
-
Electrical Insulation: With excellent electrical insulators, even at elevated temperatures, they still have good dielectric strength.
-
Low Density: Its density is around 3.6 g/cm3 for 92% ceramic wear linings, only half of the steel, which can greatly reduce the equipment load to save the energy.
