ZIRCAR Ceramics’ Alumina Type SALI-2 is a premium grade combination of polycrystalline alumina fibers tightly bound in a high-purity inorganic mullite binder matrix.
SALI-2 exhibits superior hot strength and dimensional stability in applications with temperatures to 1800°C (3192°F). SALI-2’s fine, open-pore, low-density structure gives it excellent thermal insulating properties. Its low CTE gives SALI-2 very good thermal shock resistance in severe conditions. SALI-2 is machinable to tight dimensional tolerances. SALI-2 is pre-fired, contain no organic binders and will produce no smoke or odors when heated. It has excellent resistance to chemical attack and is not affected by oil or water. It is, however, affected by hydrofluoric acid, phosphorous acid and strong alkalis.
