摘要
甲酸钇分为无水甲酸钇和二水甲酸钇,本文对这两种晶体材料的研制作了进一步的探讨。测绘了2％甲酸水溶液中甲酸钇溶解度曲线和过饱和度曲线。以30％甲酸水溶液为溶剂,在80℃恒温蒸发下得到透明的外形完整的Y(HCO_2)_3小晶体。探讨了不同溶剂与不同甲酸浓度对Y(HCO_2)_3·2H_2O晶体生长的影响;生长出较大尺寸光学质量的Y(HCO_2)_3·2H_2O晶体。
Yttrium formates include anhydrous yttrium formate andyttrium formate dihydrate. The solubility and supersaturation curves of yttri-um formates in 2% formic acid-water solution are given in this paper. Andusing 30% formic acid-water solution as a solvent, transparent and intactcrystals of anhydrous yttrium formate were obtained. On the basis of theinvestigation of the of different solvents and different formic acid concentra-tions upon the growth of yttrium formate crystals are discussed large sizeoptical quality yttrium formate monocrystals have been obtained.
