摘要：
Hot extrusion processing of YBa//2Cu//3O//y powder was examined. The starting powder was prepared from Y//2O//3, BaCO//3 and CuO powders using the conventional ceramic procedure. The bullet was preheated at a temperature from 700 degree to 1000 degree C for 5 minutes and extruded by pressing at a maximum load of about 40 tons. Hardness measurement after extrusion showed that the processing had a good effect on densification of the ceramic.
