Recent study on the defect structures in transition metal monoxides VO
x and NbO, and in stabilized zirconias Zr (Ca) O
2-x and Zr (Y) O
2-x has been reviewed. The diffuse scattering from VO
x and TiO
x was compared with the characteristic diffuse scattering observed in transition metal carbides and nitrides with NaCl-type structure. The reason for the existence of a large number of vacancies in transition metal compounds was explained in terms of their electronic structures. In addition, recent progress on the quantitative measurements and analyses of X-ray diffuse scattering from oxides has been stressed.
