Microstructure of Spark Plasma-Sintered Silicon Nitride Ceramics
Nanoscale Research Letters, 2017 The microstructure and phase composition of the high-content Al2O3-Y2O3-doped spark plasma-sintered silicon nitride were investigated. Fully dense silicon nitride ceramics with a typical α-Si3N4 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)

Transparent polycrystalline alumina using spark plasma sintering: Effect of Mg, Y and La doping [PDF]
, 2010 Transparent polycrystalline alumina (PCA) is a promising replacement for sapphire. Its optical properties however are highly dependent on the grain size and residual porosity which need to be controlled for real inline transmittances (RIT), that are high
