In the paper, the general law of oxalate precipitation reaction is kinetic analysed; the process of decreasing partical size of yttrium oxide is studied by the methods of decreasing growing velocity of crystal and increasing degree of supersaturation of solution. This process is suitable for the batch production of 99. 999% yttrium and the impurities can not be introduced.
