摘要	Zinc aluminate (ZnAl2O4, 2 O 4 , ZA) ceramic plays an important role in the development of industry and technology because of its many excellent characteristics. ZA ceramic was prepared by solid-state reaction sintering at 1550 degrees C from bauxite and zinc oxide (ZnO). The effects of different mass ratios of bauxite to ZnO and milling time on the densification, linear shrinkage, porosity, strength and microstructure of ZA ceramic were investigated. It is found that as the relative content of bauxite decreases, the strength of ZA ceramic first increases and then decreases. In addition, suitable milling time is beneficial to improve the performance of ZA ceramic, but too long milling time will be detrimental to its performance. As the mixture with 1:1 of mass ratio of bauxite to ZnO is milled for 5 h, the prepared ZA ceramic has the best performance, 4.79 g/cm3 3 of bulk density, 3.53 % of apparent porosity, 177.38 MPa of flexural strength and 523.62 MPa of compressive strength.
