Mullite-zirconia ceramic composites are prepared by reaction sintering of plasma spheroidized (PS) zircon-alumina powders in a spark plasma sintering (SPS) system at 1000, 1100, 1200 and 1300 °C with duration of 10 and 30 min. At SPS temperature of 1000 °C, evidence of zircon decomposition is detect...
