文摘

Pyrohydrolysis of SmF3 obeys the phase boundary rate law. Sm2O3 was generated on the surface layer with parceled SmOF kernel particles. The shrinking core model can be used to describe the mechanism of SmF3 pyrohydrolysis. Rate-determining step of pyrohydrolysis was the surface reaction control.
