occupying the octahedral holes. Notice that the octahedral holes are along the edges (for a net of three cations) and in the center of the cube (one more cation). Thus we have four anions (FCC) and ...

THE effect known as the Widmanstatten structure is shown most clearly in those meteoric nickel-iron alloys in which the percentage of nickel lies between certain limits, roughly, from 7 to 14.

Researchers from Kyoto University have achieved a significant advancement in materials science by developing the world's first three-dimensional van der Waals open frameworks (WaaFs). This innovation ...

The general formula is AB 2 O 4. The oxygens form an fcc lattice. The A cations occupy tetrahedral holes, and the B cation occupy octahedral holes. It then follows that 1/8 of the tetrahedral holes ...
