Synthesis and Properties of Mullite-Sialon-ZrB2Materials Produced Using a Spark-Plasma Technique

The sialon-to-ZrB2 ratio during spark-plasma sintering at pressing load 75 MPa and 1200 - 1600 degrees C influenced the phase composition, Si3N4 and Al2O3 contents in sialon, microstructure and grain size of crystalline phases, relative density, open porosity, linear shrinkage, physicomechanical properties, and the linear correlation between the elasticity modulus and compressive strength of mullite-sialon-ZrB2 samples.
