摘要： 用透射电子显微镜观察了电子辐照对α-LiIO3晶体结构的影响。α-LiIO3经100keV能量中等强度的电子束辐照后,最初转变为γ-LiIO3继而转变为Li2O和另一种新的、可能是非化学比的Li—O化合物,称之新产物X。若用强电子束进行辐照,则α-LiIO3迅速熔化。此时减弱电子束或停止辐照,均能使熔融物质凝固成上述新产物X,新产物X在电子束辐照下逐渐转变为Li2O和金属锂。从新产物X转变为Li2O的相变有一定程度的可逆性。此外发现,在电子束辐照下,α-LiIO3单晶的结构变化有明显的各向异性。

Abstract： The electron irradiation effects on the crystal structure of α-lithium iodate (α-LiIO3) have been observed by TEM. Under the irradiation of medium-intense electron beam with energy 100 KeV, α-LiIO3 transforms into γ-LiIO3 at first and then into Li2O and an other new type of Li-O compound which is probably a nonstoichiometric one and re-fered to as X compound. If the irradiation is carried out with more intense electron beam, α-LiIO3 crystal melts quickly. In that case, either a decrease in intensity of electron beam or a break in irradiation leads to recrystallization of the melted substance in the form of X compound which gradually transforms into Li2O and metal Li under subsequent electron irradiation. The phase tansformation form X compound into Li2O is reversible to certain extent. Besides, it is found that the electron irradiation effects on the structure of α-lithium iodate monocrystal is clearly anisotropic.
