| Abstract: | The chemical compositions and their functions,production technical process and outline,microstructure,properties and application of dense Cr2O3 refractory products were introduced,and the moulding and firing processes were mainly discussed.The results show that the oxygen partial pressure of firing atmosphere has important effect on the densification degree of dense Cr2O3 refractory products;the dense Cr2O3 refractory products with a certain densification degree can be produced by controlling firing atmosph... |
