  • mp-18900: MgV2O4 (cubic, Fd-3m, 227)

    materialsproject.org/materials/mp-18900 MgV2O4 is Spinel structured and crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Mg2+ is bonded to four O2- atoms to form MgO4 tetrahedra that share corners with twelve VO6 octahedra. The corner-sharing octahedra tilt angles range from 58–59°. There are three shorter (2.00 Å) and one longer (2.01 Å) Mg–O bond lengths.
  • Ilmenite: An ore of titanium | Uses and Properties

    geology.com/minerals/ilmenite.shtml What is Ilmenite? Ilmenite is a common accessory mineral in igneous rocks, sediments, and sedimentary rocks in many parts of the world. Apollo astronauts found abundant ilmenite in lunar rocks and the lunar regolith. Ilmenite is a black iron-titanium oxide with a chemical composition of FeTiO 3.. Ilmenite is the primary ore of titanium, a metal needed to make a variety of high-performance alloys.
