  • Synthesis of rare earth monoxides
    作者:J.M. Leger、N. Yacoubi、J. Loriers
    DOI:10.1016/0022-4596(81)90436-9
    日期:1981.3
    parameter consideration it is concluded that these compounds are the rare earth monoxides. For Ln =Gd, Dy, Tm, no reaction is observed at 50 kbar and 1000°C. The rare earth monoxides show a variety of properties: LaO, CeO, PrO, and NdO are metallic with the rare earth in the trivalent state; EuO and YbO are semiconductors with the rare earth in the divalent state; SmO is metallic with samarium in an intermediate
    已经计算出从稀土属和倍半氧化物形成离子或属一氧化物的标准吉布斯能量变化。在高压下,应获得离子一氧化and和较轻的稀土属一氧化物,通过带式设备在15–80 kbar和500-1200°C的温度范围内进行的实验证实了这一点。对于Ln= La,Ce,Pr,Nd,Sm,从每个反应获得面心立方化合物。电池参数分别为5.144、5.089、5.031、4.994和4.943±0.005A 3。该化合物呈黄色,具有属光泽。从化学分析和细胞参数考虑可以得出结论,这些化合物是稀土一氧化碳。对于Ln= Gd,Dy,Tm,在50kbar和1000℃下未观察到反应。稀土一氧化物具有多种特性:LaO,CeO,PrO和NdO是属,稀土元素为三价态。EuO和YbO是稀土元素为二价态的半导体。SmO是属的,sa的中间价态接近3。
  • Temperature-Dependent Rate Constants for the Reactions of Gas-Phase Lanthanides with O<sub>2</sub>
    作者:Mark L. Campbell
    DOI:10.1021/jp991647c
    日期:1999.9.1
    The reactivity of the gas-phase lanthanide atoms Ln (Ln = La-Yb with the exception of Pm) with O-2 is reported. Lanthanide atoms were produced by the photodissociation of [Ln(TMHD)(3)] and detected by laser-induced fluorescence. For all the lanthanides studied with the exception of Yb, the reaction mechanism is bimolecular abstraction of an oxygen atom. The bimolecular rate constants (in molecule(-1) cm(3) s(-1)) are described in Arrhenius form by k[Ce((1)G(4))] = (3.0 +/- 0.4) x 10(-10) exp(-3.4 +/- 1.3 kJ mol(-1)/RT); Pr(I-4(9/2)), (3.1 +/- 0.7) x 10(-10) exp(-5.3 +/- 1.5 kJ mol(-1)/RT); Nd(I-5(4)), (3.6 +/- 0.3) x 10(-10) exp(-6.2 +/- 0.4 kJ mol(-1)/RT); Sm(F-7(0)), (2.4 +/- 0.4) x 10(-10) exp(-6.2 +/- 1.5 kJ mol(-1)/RT); EU(S-8(7/2)), (1.7 +/- 0.3) x 10(-10) exp(-9.6 +/- 0.7 kJ mol(-1)/RT); Gd(D-9(2)), (2.7 +/- 0.3) x 10(-10) exp(-5.2 +/- 0.8 kJ mol(-1)/RT); Tb(H-6(15/2)), (3.5 +/-. 0.6) x 10(-10) exp(-7.2 +/- 0.8 kJ mol(-1)/RT); Dy(I-5(8)), (2.8 +/- 0.6) x 10(-10) exp(-9.1 +/- 0.9 kJ mol(-1)/RT); Ho(I-4(15/2),), (2.4 +/- 0.4) x 10(-10) exp(-9.4 +/- 0.8 kJ mol(-1)/RT); Er(H-3(6)), (3.0 +/- 0.8) x 10(-10) exp(-10.6 +/- 1.1 kJ mol(-1)/RT); Tm(F-2(7/2)), (2.9 +/- 0.2) x 10(-10) exp(-11.1 +/- 0.4 kJ mol(-1)/RT), where the uncertainties represent +/-2 sigma. The reaction barriers are found to correlate to the energy required to promote an electron out of the 6s subshell. The reaction of Yb(S-1(0)) with O-2 reacts through a termolecular mechanism. The limiting low-pressure third-order rate constants are described in Arrhenius form by k(0)[Yb(S-1(0))] = (2.0 +/- 1.3) x 10(-28) exp(-9.5 +/- 2.8 kJ mol(-1)/RT) molecule(-2) cm(6) s(-1).
