Investigation on Al-Cr2O3-Al2O3 sliding gate performance

摘要：

　　High performance A1-Cr2O3-A12O3 sliding gate are made from tabular corundum,white fused corundum,aluminum powder,and chromium oxide powder.Phenolic resin is used as binder.The properties of the A1-Cr2O3-Al2O3 sliding gates with the different content of chromium oxide(mass percent 3%,6%,9%,12%,15%) which are made from different processes (dried at 200℃ in air,fired at 1300 ℃ in N2 and fired at 1450 ℃ in CO),are researched respectively.The results show that in different processes,the samples which contain 6% chromium oxide powder have higher cold crushing strength and hot modulus of rupture.After fired in N2,the new phases Al8Cr5 (1327℃),AlN are formed,and after fired in CO,AlsCr5,Al2OC and Cr3C2 are formed.These materials are contributed to improve the mechanical properties of samples.The samples fired in N2 have the best performance.
