lithium oxide and transition metal halides MXn (M = Ti, Zr, Hf, V, Nb, Ta, Mo, W, Fe, Mn) at 800°C for 2–12 h produces crystalline lithium transition metal oxides Li2MO3 (M = Ti, Zr, Hf, Mn), Li3MO4 (M = V, Nb, Ta), Li2MnO3 Li2Fe3O4 and Li2MO4 (M = Mo, W). For M = Cr, Co, Ni, Cu and Zn the reaction produces the metal oxides Cr2O3, NiO, CuO, ZnO and Co3O4. The metal oxides and lithium metal oxides were
氧化锂和过渡金属卤化物MX n(M = Ti,Zr,Hf,V,Nb,Ta,Mo,W,Fe,Mn)的混合物在800°C下热解2–12小时,生成结晶的锂过渡金属氧化物Li 2 MO 3(M = Ti,Zr,Hf,Mn),Li 3 MO 4(M = V,Nb,Ta),Li 2 MnO 3 Li 2 Fe 3 O 4和Li 2 MO 4(M = Mo ,W)。当M = Cr,Co,Ni,Cu和Zn时,反应生成金属氧化物Cr 2 O 3,NiO,CuO,ZnO和Co 3 O 4。通过X射线功率衍射对金属氧化物和锂金属氧化物进行表征。SEM / EDAX,FT-IR和磁矩测量。
