Amount of reduction of NiO in 2 hr. in H2 at temperatures 200°-425° shows maximum at 265° and 350° and is essentially zero in the ranges 300°-340° and 355°-400°. The metallic Ni formed is estimated by a magnetic method. The 265° maximum may be related to the dilation anomaly in NiO. The general low rate in the 300°-400° range appears related to the loss of antiferromagnetism of NiO in this range. The sharp maximum at 350° appears related to the Curie point of Ni.
