Description

ZIRCAR Ceramics’ Alumina Type ZAL-15AA is an engineered low-density rigid refractory structure composed of high-alpha polycrystalline alumina fibers and high-purity inorganic alumina binders. ZAL-15AA’s uniformly-bound fine open-pore structure makes it an excellent thermal insulator with good machinability. ZAL-15AA exhibits good hot strength and dimensional stability in industrial applications with continuous operating temperatures to 1500°C (2732°F) and withstands intermittent use to 1600°C (2912°F). The high-purity alumina binder gives this low-density fiber body a very high degree of chemical inertness and it is therefore useful in reducing atmospheres. ZAL-15AA exhibits high electrical resistivity at elevated temperatures and is also transparent in microwave and RF energy fields. ZAL-15AA is pure white and exhibits high reflectance.
ZAL-15AA is pre-fired, contains no organic binders and will produce no smoke or odors when heated. ZAL-15AA shows excellent resistance to chemical attack and is not affected by oil or water. It is, however, affected by hydrofluoric acid, phosphoric acid and strong alkalis. For more information see “Effects of Hydrogen Gas at 1450°C on Select Fibrous Alumina Insulation Products”.
