Abstract

The article discusses an energy-efficient method for producing SiC-based composites via doping with oxide eutectic compositions and batch granulometry regulation. The influence of batch granulometry on physico-mechanical properties of ceramics is studied, and fractions ratio is determined allowing us to obtain a dense material with improved strength and fracture toughness. Such ceramics shows excellent mechanical behavior and holds much promise as a structural and armor material.
