Crystal chemistry of layered Pb hydroxocarbonate minerals

Comparative Crystal Chemistry of Orthosilicate Minerals

Comparative Crystal Chemistry of Dense Oxide Minerals

Oxygen is the most abundant element in the Earth, constituting about 43 percent by weight of the crust and mantle. While most of this mass is incorporated into silicates, the next most abundant mineral group in the planet is the oxides. The oxide minerals are generally considered to be those oxygen-based minerals that do not contain a distinct polyanionic species such as OH, CO3, SO4 PO4, SiO4,...

Crystal chemistry of layered carbide, Ti3(Si0.43Ge0.57)C2

The crystal structure of a layered ternary carbide, Ti3(Si0.43Ge0.57)C2, was studied with single-crystal X-ray diffraction. The compound has a hexagonal symmetry with space group P63/mmc and unit-cell parameters a 1⁄4 3.0823(1) Å, c 1⁄4 17.7702(6) Å, and V 1⁄4 146.21(1) Å. The Si and Ge atoms in the structure occupy the same crystallographic site surrounded by six Ti atoms at an average distanc...

THE CRYSTAL CHEMISTRY OF SILICATE MINERALS WITH CHAINS OF (TiO6) OCTAHEDRA

Chains of (TiO6) octahedra occur in several crystal structures as fundamental building blocks, confirming the tendency of self-polymerization for (TiO6) octahedra. There are two topologically distinct types of chains based on linkage of (TiO6) octahedra, corner-sharing chains and edge-sharing chains. In this paper, we focus on the diversity of linkages between chains of (TiO6) octahedra and (Si...
