%X The synthesis kinetics of YBa_2Cu_30_x supercon-ductor was studied through comparing the calcina-tion (sintering) processes of different kindsof powders. It was shown that the temperatureof synthesis of YBa_2Cu_30_x phase can be loweredfrom 950℃ to 800℃ through direct calcinationof multiphase powder with uniform chemical com-position. The stress which is caused by thevolume change during synthetic reaction breaksthe particles. It facilitates the formationof highly active superfines of superconductor.
