摘要：
The effects of: - different Si3N4 powders, - different powder processing routes (mechanical-, ultrasonic-, attritor mixing of additive powders and chemical coprecipitation of metal hydroxides), - different sintering aid systems (La2O3+Y2O3, Al2O3+Y2O3, AlN+Y2O3) on microstructure and properties of hot pressed silicon nitride were evaluated and compared. All the properties: strength, hardness, toughness, Young's modulus, thermal expansion were related to the microstructural features (grain size and morphology, grain boundary phases, flaws) which are specific to a material and its process history.
