Synthesis Processes of Nano Alumina Abrasive

摘要：

　　Synthesis processes ofnano alumina abrasive precursor using precipitation method and sol-gel method were investigated in this study.Using pressureless sintering,the nano alumina abrasive was prepared.Mechanical properties of the samples were measured by using single particle compressive strength tester.The microstructures of them were examined by using field emission scanning electron microscopy (FESEM).The results indicated that the performance and microstructure of the samples are greatly relative to the synthesis processes.Compared with samples prepared by precipitation method,the samples prepared by sol-gel method have higher compressive strength,smaller grain size and more uniform microstructure.The average grain size of the alumina abrasive was below 100nm.
