Alumina-Silica Type ASQ-20 General Information ZIRCAR Ceramics’ Alumina-Silica Type ASQ-20 is a premium-grade, medium-density combination of shot -free refractory ceramic fibers (RCF) and high-purity inorganic alumina binder. Initially designed for use as baffles and spacers in injection nozzles on SCAL thin-strip casters, ASQ-20 exhibits low density and low thermal conductivity. ASQ-20 exhibits good hot strength and resiliency making it virtually immune to thermal shock and changes in molten aluminum head pressure. As its alumina binder is uniformly distributed ASQ-20 is machinable to very well controlled dimensional tolerances. When used in contact with molten aluminum it does not require a coating of Boron Nitride. Its fine colloidal alumina particles also make it suitable for use as a glass slumping and fusing mold. ASQ-20 is pre-fired contains no organic binders and will produce no smoke or odors when heated. ASQ-20 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. ZIRCAR Ceramics, Inc. PO Box 519 Technical Data Bulletin 100 N.
