摘　　要：Four ytterbium deuteride samples with D/Yb atomic ratio of 2.90、2.53、2.23 and 2.06 were prepared under high pressure metal system at 400℃,and initial deuterium pressure is 6.53MPa、3.41MPa and 1.32MPa respectively.Results indicate that satureated time of deuterium by ytterbium sample and D/Yb atomic ratios are correlated with initial deuterium pressure.XRD analytical results indicate that YbD 2.90 has a facc structure with a=0.5205nm.YbD 2.90 decomposed at 600℃,the product is YbD 2.06 and it has two phases,they are orthorhombic and another face center cubic structure.YbD 2.53 and YbD 2.23 are composed by orthorhombic and face center cubic ytterbium deuterides.Four ytterbium deuteride samples with D/Yb atomic ratio of 2.90、2.53、2.23 and 2.06 were prepared under high pressure metal system at 400℃,and initial deuterium pressure is 6.53MPa、3.41MPa and 1.32MPa respectively.Results indicate that satureated time of deuterium by ytterbium sample and D/Yb atomic ratios are correlated with initial deuterium pressure.XRD analytical results indicate that YbD 2.90 has a facc structure with a=0.5205nm.YbD 2.90 decomposed at 600℃,the product is YbD 2.06 and it has two phases,they are orthorhombic and another face center cubic structure.YbD 2.53 and YbD 2.23 are composed by orthorhombic and face center cubic ytterbium deuterides.
