| 摘 要： | 在流体静压力到10kbar范围内,采用DTA技术研究了压力对NH4IO3及其固溶体Kx(NH4)1-xIO3的相变温度(Tc)的影响。实验结果表明,虽然固溶体的相变温度Tc随K+组分的增加而减小,但是dTc/dP值却同K+组分无关。这意味着在压力下IO3-离子的伸长对Tc随压力增加起主要作用。

| Abstract: | The effects of hydrostatic pressure on the transition temperatures Tc of NH4IO3 and its solid solutions Kx(NH4)1-xIO3 have been investigated by means of differential thermal analysis (DTA) up to 10 kbar. The experimental results of Kx(NH4)1-xIO3 solid solutions indicates that the dTc/dP values are independent of the concentration of K+, although Tc decreased with increasing concentration. This appears to imply that the IO3- ions elongation under pressure will play a more important role in the pressure effect on the rising of Tc. |
