Lithium Trimolybdate, Li₂O.3MoO₃.7H₂O

Lithium Trimolybdate, Li₂O.3MoO₃.7H₂O, is obtained by evaporating a solution of the tetramolybdate, removing any crystals of molybdic acid and concentrating further, when long slender needles separate. When fused and ignited in hydrogen, a dark violet lustrous solid, resembling the alkali tungsten bronzes, is obtained.
