Description

ZIRCAR Ceramics’ Alumina Type ZAL-12 is a low-density, rigid refractory structure, composed of high-alpha polycrystalline alumina fibers and high-purity inorganic binders. ZAL-12 was engineered to deliver the lowest possible density and is manufactured to a tight +/-1.0 pcf density. Despite its very low density, this unique material also exhibits good machineability. ZAL-12 exhibits high electrical resistivity at elevated temperatures and is also very transparent in microwave and RF energy fields. ZAL-12 is pure white and exhibits high reflectance.
ZAL-12 is pre-fired, contains no organic binders and will produce no smoke or odors when heated. ZAL-12 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.
