摘要：
The effective mechanochemical method of the synthesis of lanthanum cobaltite from lanthanum and cobalt was developed. The temperature of the synthesis was decreased to 873 K by means of the mechanical activation. It was allowed to obtain lanthanum cobaltite in the state of the high dispersion and the high catalitic activity.
