氢化物是一个非常广阔的领域.人们对它们在常压下的性质已进行了大量的研究,而且氢化物在科学研究和工业生产中已有了广泛的应用.然而,对它们在高压下的性质还研究得相当少.近一些年来,研究氢化物在高压下的性质以及金属化相变已引起了人们很大的兴趣.Straaten等曾研究了HI在高压下的性质,发现它在42.5—51GPa下发生了由绝缘体变成金属的转变.我们过去曾对LiH和AIH_3在高压下的性质进行过一些实验研究.在本工作中,我们研究了TiH_2和ZrH_2在高压下的P-V关系以及电学性质的变化,得到一些有趣的结果.这些结果在国外还未见发表过.
Hydride is a very broad field.Here, people have done a lot of research on their properties under atmospheric pressure, and hydrides have been widely used in scientific research and industrial production.However, their high pressure Nature has also been studied very little.In recent years, the study of hydride properties under high pressure and metallographic phase transition has aroused great interest.Straaten, who studied the properties of HI under high pressure and found it in 42.5- At 51 GPa, a transition from insulator to metal took place.We have conducted some experimental studies on the properties of LiH and AIH_3 under high pressure in the past.In this work, we investigated the PV relationship of TiH_2 and ZrH_2 under high pressure and their electrical properties Some interesting results have been obtained and these results have not been published in foreign countries yet.
