Product Description
High-Density Alumina Ceramic Refractory Bricks and Plates
Alumina ceramics are advanced ceramic materials based on aluminum oxide (Al₂O₃) that offer exceptional performance characteristics for demanding industrial applications. These materials provide excellent electrical conductivity, superior mechanical strength, and outstanding high-temperature resistance up to 1650°C.
Key Product Features
- High density construction with 3.85 g/cm³ for 99% alumina grade
- Exceptional thermal resistance up to 1650°C maximum use temperature
- Superior mechanical strength with 330 MPa flexural strength
- Excellent electrical insulation properties with volume resistivity >10¹⁴ Ω.cm
- Zero water absorption and gas permeability for complete sealing
- High hardness rating of HRA 82 for superior wear resistance
