Notes:
Aluminum phosphate is one of the best inorganic binders, and the addition of chromium oxidecan improve the properties of the binder. In this work, the phase evolutions in chromium phosphatesystem and aluminum-chromium-phosphate system during heat-treatment were investigated. The initialbinder solutions were prepared by dissolving Al(OH)3 and Cr2O3 in aqueous H3PO4 solution. The bindersolutions consolidated at 100°C. The as-consolidated products were heated at different temperature. Theexperimental results showed the phase evolution of the consolidated products as: amorphous phase in300~800°C, Cr(PO3)3 and Cr4(P2O7)3 in 900~1200°C for chromium phosphate system binder; amorphousphase in 300~1000°C, Cr(PO3)3 and AlPO4 in 1100°C, Cr4(P2O7)3 and AlPO4 in 1200°C for aluminumchromium-phosphate system binder. The addition of chromium oxide demonstrates to strengthenamorphous network, which further improves the thermal stability
