Abstract

Processing of multi-phase ceramic composite materials using chemically bonded ceramics as a binding agent appears to be a promising route for fabricating complex-shaped structures. In a zirconia-calcium aluminate ceramic matrix composite, the hydraulic property of fine, monocalcium aluminate (CaAl2O4) powders was used to prepare strong prefired bodies. The changes in the physical characteristics of the composite during the conversion from a chemically bonded compact into a sintered composite were studied using thermogravimetric analyses (TGA), X-ray diffraction and scanning electron microscopy. The density and the hardness of the chemically bonded and sintered composite were measured.
