近些年来,随着激光技术的飞快发展,一水甲酸锂单晶作为一种优良的非线性光学材料而出现,受到应有地重视。一些学者对甲酸锂的结构、性能、单晶的各种特性等方面进行了广泛研究,获得了很多数据;但不完全,有的很不准确。而对甲酸锂比较完整的热分析尚未见到报导。为了了解、掌握甲酸锂的性能,更好地研制高质量的单晶,以及解决它的使用、保存等问题,对甲 In recent years, with the rapid development of laser technology, lithium monohydrochloride monocrystal appears as an excellent nonlinear optical material, deserved due attention. Some scholars have conducted extensive research on the structure, properties, and various characteristics of single crystals of lithium formate, and obtained a lot of data; however, they are incomplete and some are inaccurate. Thermal analysis of lithium formate has not been reported yet. In order to understand and master the performance of lithium formate, to better develop high-quality single crystal, and to solve its use, preservation and other issues, a
