摘要：
Extremely dense zirconia-mullite composites were developed by reaction sintering of microcalcined fine alumina powder and zircon flour taken in different ratios with Cr2O3 as an additive. The powder mixes were isostatically pressed and sintered at 1550 degrees C. The sintered compacts were characterised by different physicomechanical properties, microstructure developed and phase compositions. Cr2O3 exhibited positive influence up to certain level of addition on the thermomechanical properties of reaction sintered zirconia-mullite composites including corrosion resistance and microstructure.
