摘要：

白钨矿型激光晶体LiREF 4仅对于分别为元素Er、Tm、Yb、Lu或可能的Y中的一种的RE才全等熔化。当RE = Eu、Gd、Tb、Dy或Ho时，相应的白钨矿在形成相应的稀土氟化物的条件下发生包埋熔融。含两种或两种以上RE的LiREF_4混晶的熔化行为尚不清楚。当RE为Gd和Lu的混合物时，富Gd固溶体在形成（Gd，Lu）F3的情况下包晶熔化，富Lu固溶体直接熔化而不形成其它固相。

英文摘要：

The scheelite type laser crystals LiREF4 melt congruently only for RE being one of the elements Er, Tm, Yb, Lu, or possibly Y, respectively. For RE = Eu, Gd, Tb, Dy, or Ho the corresponding scheelites undergo a peritectic melting under the formation of the corresponding rare earth fluoride. The melting behavior of LiREF4 mixed crystals with two or more RE is not yet known well. If RE is a mixture of Gd and Lu, Gd rich solid solutions melt peritectically under formation of (Gd,Lu)F3 and Lu rich solid solutions melt directly without formation of other solid phases.
