二元相图中稳定化合物活度的计算方法 - However , te - rich phases and point defects with high concentration were found locally . not only the vapor - solid equilibrium but also the vapor - liquid - solid equilibrium should be considered for the annealing of the crystals with te - rich phases . by analyzing the phase diagrams of cd - te and p - t plot of cd1 - xznxte ( x = 0 . 04 ) , it was concluded that for the purpose of rem
本文通过仔细分析cd . te二元相图和cd卜龙znxte ( x = 0 . 04 )的p一t相图，认为为了去除富te相，获得稳定的电学性能，退火时晶片温度应小于115ok ，气氛环境的总压力应小于pcs (对cdte ， pc汹 - Abstract : study is made of recovery of organic reagents during the preparation of ultrafine powder by metal alcoxides hydrolysis . the phase diagrams of isopropanol - benzene system and isopropanol - benzene - water system have been plotted , based on which , isopropanol and benzene can be recovered and recirculated by distillation - rectification process . the recovery and reused rate of alcohol and benzene are above 75 % . so both the environmental pollution and cost of ultrfine powder are reduced
文摘:对醇盐水解法制备超细粉末过程中有机试剂的回收进行了研究，绘制了异丙醇-苯的二元相图和异丙醇-苯-水的三元相图，在此基础上采用蒸馏-精馏的方法对制备体系中的异丙醇和苯进行回收，将有机试剂循环使用，使醇和苯的回收利用率达75 %以上，因而减少了环境污染，并降低了粉末成本。 - According to the nb - si phase diagram , the temperature of 1550 ? , which is lower than the eutectoid transformation temperature of nbssi ( 1783 ? ) , is chosen for heat - treatment . according to the present conditions of the furfaces , heat - treatment by stages is first proposed for the nb - si system intermetallic composites to keep the furface in good conditions . the results indicate that the equilibrium nb + nbssia dual - phase microstructure of the nb - si system intermetallics forms gradually via such eutectoid reaction as nbasi ? nb + nbssis with the heat - treatment time
根据nb - si二元相图，选择略低于nb _ 3si共析转变温度t _ f = 1783的1550对铸态nb - si系金属间化合物进行不同时间( 25h - 100h )的热处理，并根据目前国内和我院热处理炉的现状，首次提出采用分段热处理的方法来解决nb - si合金热处理温度高、连续热处理时间过长而影响热处理炉寿命的困难。
