Preparation and Identification of Ca2Zn4Ti15O36-A New Structure Type

A ternary oxide containing Ca, Zn, and Ti was characterized by chemical and X‐ray analysis as Ca2Zn4Ti15O36. It crystallizes with rhombohedral symmetry in space group R3, or possibly R3. The hexagonal cell dimensions are α= 1.0371±0.0005 and c=2.0938±0.0010 nm; density is 4.18 g/cm3. Ca2Zn4Ti15O36 i...

Description
Summary:A ternary oxide containing Ca, Zn, and Ti was characterized by chemical and X‐ray analysis as Ca2Zn4Ti15O36. It crystallizes with rhombohedral symmetry in space group R3, or possibly R3. The hexagonal cell dimensions are α= 1.0371±0.0005 and c=2.0938±0.0010 nm; density is 4.18 g/cm3. Ca2Zn4Ti15O36 is the first member of this new type of structure to be synthesized; several other examples were also prepared. The mineral davidite is probably isostructural with these pure synthetic compounds and the mineral senaite appears to have a closely related structure.
