Abstract (en)
[origin: WO0030999A1] A new refractory insulating aggregate for high temperature applications has been developed. The product contains approximately 92 % Al2O3 and 7.5 % CaO; its mineralogical composition is calcium hexaluminate. The product is a homogeneous material with a high porosity of typically 75 % and a small pore radius of 0.5-2.5 mu m. The product is produced by a process which includes hydrothermal hardening in an autoclave.
