EFFECT OF GRINDING OF Y₂O₃, BaCO3 AND CuO ON SYNTHESIS OF YBa₂Cu₃O₇ 

B. Plešingerová, A. Buchal, V. Šepelák, K. Tkáčová

The very fine and surface reactive powder mixture was prepared by highly intensive short time mill grinding of the components Y₂O₃, BaCO₃ and CuO. Pure YBa₂Cu₃O₇ created by reaction of the components of grinding mixture at temperature 900 - 950°C. The temperature of the synthesis of YBa₂Cu₃O₇ decreased owing to the grinding about 50 to 100°C. Lower temperature of the synthesis had a positive effect on the purity of the final product.
