室温下经过不同的高压(最高为80kbar)作用后的β-LiIO_3的X射线衍射实验表明:1)受压后的β-LiIO_3在大气中发生的β→α相转变中,高压的作用是促使α相晶核形成。成核率N与压力P的关系接近于N∝e~(kp)(k=26.8/bar);2)受压力处理后的β-LiIO_3中的α相量在大气中的明显增加,可归结为大气中水分子在α相晶核表面上解离产生的氢离子引起了α晶核的迅速长大,这一论断受到了H~+注入产生类似效应的支持。
X-ray diffraction experiments of β-LiIO_3 at room temperature under different high pressures (up to 80kbar) show that: 1) In the β → α phase transformation of β-LiIO_3 under atmospheric pressure, the effect of high pressure is to promote α-phase nucleus formation. The relationship between nucleation rate N and pressure P is close to Nαe ~ (kp) (k = 26.8 / bar); 2) The significant increase of α phase in β-LiIO_3 after pressure treatment in the atmosphere can be attributed to Hydrogen ions generated by the dissociation of water molecules on the α phase nucleus in the atmosphere caused the rapid growth of α nuclei, which was supported by the similar effect of H ~ + implantation.
