ZIRCAR Compositized 18000C Thermal Insulation

Advanced Battery Technology, Dec 2004

ZIRCAR Ceramics, Inc.'s Alumina Insulation Type AL-28/1800. AL-28/1800 was developed using a new process wherein precisely controlled raw materials are pyrotechnically treated, resulting in a compositized fiber/binder microstructure. This produces a strong, stable product for OEM furnace builders and other producers of ultra high temperature thermal process systems.

AL-28/1800 exhibits a bulk density of 0.44g/cc (28pcf) with a composition of 80% Al^sub 2^0^sub 3^, 20% SiO^sub 2^. At 18000C AL-28/1800 exhibits 3% linear shrinkage and a 17000C sag resistance of 0.2%. Its MOR is 1.82MPA (264psi) with a compressive strength of 1.38MPA ( 199psi).

AL-28/1800 is now produced in a variety of standard flat boards in sizes up to 18'' × 24'' × 2''. It is easily fabricated into custom insulation components and is readily cemented into "butcher block" furnace roofs.
