Strong and Super-Strong Ceramics Based on Aluminum Oxide and Partly Stabilized Zirconium Dioxide

The authors describe the results of development of strong and superstrong ceramics based on aluminum oxide and partly stabilized zirconium dioxide using highly disperse powders and the methods of hydrostatic and hot molding and sintering in a gasostat. Ceramic materials based on aluminum oxide have strength of 300 – 750 MPa and materials based on partly stabilized zirconium dioxide have strength of 800 – 2500 MPa. These materials can be widely used in various sectors of engineering due to their high strength, wear resistance, and hardness.
