用ESR法研究M(OH)_2(M=Mg,Ca,Sr,Ba)与V_2O_5焙烧过程中的固相反应

Study on Solid Phase Reactions of M(OH)_2(M=Mg,Ca,Sr,B a) and V_2O_5 in Baking Process by ESR

通过ESR研究结果发现V2 O5在焙烧过程中可以失去晶氧 ,生成V4 + ;当加入一定量的Mg2 + ,Ca2 + ,Sr2 + 和Ba2 + 时 ,促进了这一反应的进行 .

Through the research of ESR, it has be en found that during heating V 2O 5 will lose the oxygen of crystal lattice a nd then turn to V 4+ . If a litte of Mg 2+ ,Ca 2+ ,Sr 2+ and Ba 2+ are added to V 2O 5, the reaction of solid phase will be sped up.
