Polycrystalline alumina fiber refractory board

Product parameter

Polycrystalline alumina fiber refractory board
Product classification:
The total content of polycrystalline alumina fibers is>95%, among which ALPHA AL2O3:>90% without organic additives, ultimate temperature resistance: 1800 ℃, fiber diameter: 2-4 μ M
Application scope:
1. High temperature insulation for military research, aerospace, nuclear industry, etc
2. Insulation board for high-temperature kiln industry
3. Other high-temperature insulation fields
5. Thermal insulation raw materials for high-temperature resistant industries
6. High temperature ceramic insulation heat-resistant plate
Product features:
1. Polycrystalline alumina fiberboard is a high-temperature resistant and ultra lightweight insulation material. Maintaining a polycrystalline microcrystalline structure at high temperatures ensures good heat resistance and high strength.
2. Low heat storage capacity and excellent heat shock resistance
3. Low thermal conductivity and good high-temperature stability
4. Good processability.
Appearance:
Standard specifications: 600 * 1000 * 25mm, 900 * 1000 * 25mm, large quantities can be customized.
