Abstract
- We have obtained powders of garnet-type complex oxide Y 2.5 Nd 0.5 Al 5 O 12 – x vol.% SiC (x = 0, 10, 20) using wet chemistry techniques. The ceramics based on the studying compounds were sintered using Spark Plasma Sintering (SPS) (Т sintering = 1320-1350 °С, Р = 80 MPa, t sintering = 7 min, t shrinkage = 2 min) with relative density ~98%. Microstructure of the obtained composites and influence of the concentration of silicon carbide on their mechanical (microhardness, fracture toughness) properties were investigated.
