Magnetic pulse compaction of oxide powders of the (ZrO₂ – y₂O₃)–Al₂O₃ system

Technology for manufacturing products by magnetic pulse compaction from oxide powders of the (ZrO₂ – y₂O₃)–Al₂O₃ system is presented in the paper. Diagram of the magneticpulse press with its operating principle being based on Ampere's law is given. Physical and mechanical properties of the obtained compacts are determined. The main feature of the designed technology is the reduced sintering temperature (200 °C) and the acquired fine-grained structure of the products. Another significant advantage achieved by applying the technology is the possibility for manufacturing fine-grained structure ceramic products with high mechanical properties.
