Abstract

Silicon nitride has been a prime candidate material for active components of future high temperature heat engines, particularly gas turbines. Its high temperature properties such as oxidation resistance, strength, creep and stress-rupture are critically dependent upon additives which are necessary for consolidation of Si3N4. powders by hot-pressing into pore free ceramics. Typical additions, MgO, Y2O3, ZrO2 at a few percent level, degrade high temperature properties severely.
