MIZZOU CASTABLE is a high alumina material for use to 3000F. It has excellent resistance to numerous different slags, resists vitrification, and actually shows expansion rather than shrinkage at high temperatures. MIZZOU CASTABLE also has superior resistance to spalling and high strength throughout its entire temperature range. Typical applications are combustion chambers, low temperature incinerators, air heaters, boilers, burner blocks, aluminum furnace upper sidewalls and roof regions, forge furnaces, and iron foundry ladles.Maximum Temperature 3000F 1650Clb/ft3 g/cm3Material Required 138 2.21Bulk DensityAfter 220F (105C) 143 2.29After 1500F (815C) 138 2.21Silica (SiO2) 34.1%Alumina (Al2O3) 58.8%Iron Oxide (Fe2O3) 1.3%Titania (TiO2) 2.3%Lime (CaO) 2.8%Magnesia (MgO) 0.3%Alkalies (Na2O & K2O) 0.4%
