The phase diagram of system NdCl_3-LiCl-KCl has been investigated by DTA.Six surfacescorresponding to the prhnary crystallization of NdCl_3,LiCl,KCl,γ-KCl·NdCl_3,β-3KCl·NdCl_3 and 2KCl·NdCl_3 respectively,eleven univariant lines related to the sec-ondary crystallization,two ternary eutectics E_1(70.5wt-% NdCl_3+8.0wt-% KCl,360℃)and E,(5.0wt-% NdCl_3+ 53.0wt-% KCl,355℃)and one ternary peritectic P(67.0wt-% NdCl_3+10.0wt-% KCl,375℃)were found.It is also chtrified that this studyon the system NdCl_3- KCl differs from previous work in the two transition temperatures:e_1(77.0 wt-% NdCl_3,484℃),e_2(40.0wt-% NdCl_3,620℃),p(70.0wt-%NdCl_3,610℃),3KCl·NdCl_3(690℃)and two reactions:α-3KGl·NdCl_3β-3KGl·NdCl_3 (355℃)β-SKGl·NdCl_3γ-3KCl·NdCl_3 (450℃)The eutectic point e_5(31.0wt-%LiCl,460C)is determined for the pseudobinary system3KCl·NdCl_3—LiCl.
The phase diagram of system NdCl_3-LiCl-KCl has been investigated by DTA.Six surfacescorresponding to the prhnary crystallization of NdCl_3, LiCl, KCl, γ-KCl · NdCl_3, β-3KCl · NdCl_3 and 2KCl · NdCl_3 respectively, eleven univariant lines related to the sec-ondary crystallization, two ternary eutectics E_1 (70.5wt-% NdCl_3 + 8.0wt-% KCl, 360 ° C) and E (5.0wt-% NdCl_3 + 53.0wt-% KCl, 355 ° C) and one ternary peritectic P (67.0 wt-% NdCl_3 + 10.0 wt-% KCl, 375 ° C) were found. It is also chtrified that this study on the system NdCl_3- KCl differs from previous work in the two transition temperatures: e_1 (77.0 wt-% NdCl_3,484 (40.0wt-% NdCl3,620 ℃), p (70.0wt-% NdCl3,610 ℃), 3KCl · NdCl3 (690 ℃) and two reactions: α-3KGl · NdCl3β-3KGl · NdCl3 ) β-SKGl · NdCl 3γ-3KCl · NdCl 3 (450 ° C) The eutectic point e_5 (31.0 wt-% LiCl, 460C) was determined for the pseudobinary system 3 KCl · NdCl 3 -LiCl.
