Microstructure of Spark Plasma-Sintered Silicon Nitride Ceramics

The microstructure and phase composition of the high-content Al(2)O(3)-Y(2)O(3)-doped spark plasma-sintered silicon nitride were investigated. Fully dense silicon nitride ceramics with a typical α-Si(3)N(4) equiaxed structure with average grain size from 200 to 530 nm, high elastic modulus of 288 GP...

description The microstructure and phase composition of the high-content Al(2)O(3)-Y(2)O(3)-doped spark plasma-sintered silicon nitride were investigated. Fully dense silicon nitride ceramics with a typical α-Si(3)N(4) equiaxed structure with average grain size from 200 to 530 nm, high elastic modulus of 288 GPa, and high hardness of 2038 HV were spark plasma sintered (SPSed) at 1550 °C. Silicon nitride with elongated β-Si(3)N(4) grains, higher hardness of 1800 HV, density of 3.25 g/cm(3), and Young’s modulus 300 GPa SPSed at 1650 °C was also reviewed.
