Preparation of MoSi2–SiC–ZrB2 Structural Ceramics by Free Sintering

  • Published:
Refractories and Industrial Ceramics Aims and scope

Technological conditions for preparing ceramics based on MoSi2 hardened by SiC and ZrB2 that have enhanced physicomechanical properties (relative density ≥99.1%, bending strength 480 MPa) were experimentally investigated. The developed composites could be recommended for the creation based on them of functional structural ceramics operating at elevated temperatures in an oxidizing environment.
