| Alumina (Al2 O3) has excellent thermal shock resistance, high dimensional stability and good chemical inertness, which makes our alumina fiber products ideal for fast firing cycles up to 1700°C. Our alumina fibers and textiles are made by the same unique Zircar process used for manufacturing yttria-stabilized zirconia cloths and felts. This process yields a high purity alumina fiber with only trace amounts of silica, making it more stable in hydrogen environments than the more commonly found sol-gel alumina fibers that have 3% silica. Our high purity alumina fiber and textiles are offered in six different standard product forms bulk fiber Type ALBF, two felts Types ALF-50 and ALF-100 and three types of knit cloth Types ALK-15, ALW-15 and ALW-30. Features: - Excellent Thermal Shock Resistance
- 99% Pure Alumina

- Dimensional Stability in Hydrogen
- Low Thermal Conductivity
- No Outgassing
- Six Different Product Formats Offered
- Available ‘Off the Shelf’
Application Information: - Alumina fiber textiles are used as insulation for glass melting furnaces.
- Alumina bulk fiber, Type ALBF, is used as bulk fill insulation.
- Alumina fiber textiles are used as insulation for fiber optic furnaces.
- Alumina fiber textiles are used in SOFC and PEM type fuel cells as gaskets.
- Alumina fiber cloth is used as insulation in differential scanning calorimeters (DSC’s).
