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

Аннотация

The sialon-to-ZrB₂ ratio during spark-plasma sintering at pressing load 75 MPa and 1200 – 1600°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.
