Synthesis technology of spinel AlON
摘要
The high-purity AlON ceramics,AlON/Al2O3 and AlON/AlN multiphase ceramics were prepared by pressureless sintering under nitrogen-based atmosphere with raw materials of Al2O3,AlN and Al powders. The compositions of the phase were determined by XRD,the fracture appearance was analyzed by SEM. The results indicate:the aluminum oxynitride phase in the AlON ceramics and other multiphase ceramics exist in the form of Al5O6N,whose solid-solution zone is 33.4%(mole fraction) AlN belonging to spinel structures. The average grain size of high-purity AlON is about 3 μm. The grain boundary is smooth without other phases. The density is 2.82 g/cm3,the microhardness(10 N) and about bending strength are 1 470 MPa and 94 MPa,respectively.
