  3. The low-temperature formation of mixed-metal oxides

    Yip, Thomas Wai SingUniversity of Strathclyde2011

    This thesis describes a new route to lithium molybdate, Li₂MoO₄, which involves grinding together LiOH·H₂O and MoO₃ in air at room temperature. X-ray powder diffraction data show that the formation of highly crystalline Li₂MoO₄ is largely complete after 10 min, and that this product crystallises …
