摘要
由摩尔比分别为1:2和1:8的六水氯化镍和硼砂反应得到两种镍硼酸盐样品1.25NiO·B_2O_3·4.5H_2O和NiO·B_2O_3·3.1H_2O。用XRD、TG-DSC、FT-IR和Raman等实验方法对其进行表征,样品为非晶态,确定了样品中的阴离子等,并结合化学分析结果近似确定了上述两种非晶态镍硼酸盐样品的结构组成式,前者为三元复盐,结构式为Ni[B_3O_3(OH)_5]·0.5Ni[B_2O(OH)_6]·Ni(OH)_2·4H_2O,后者结构式为Ni[B_2O(OH)_6]。
Two kinds of amorphous nickel borates samples of 1.25NiO·B2O3·4.5H2O and NiO·B2O3·3.1H2O were synthesized with nickel chloride hexahydrate and borax as reactants at the mole ratio with1：2 and 1：8,respectively.The structure and anions of the synthesized samples were characterized by XRD,TG-DSC,FTIR and Raman techniques.Approximately determined the structural formulas of synthesized samples,the former was a ternary complex salt,structural formula was Ni[B3O3（OH）5]·0.5Ni[B2O（OH）6]·Ni（OH）2·4H2O,and the latter structural formula was Ni[B2O（OH）6],in combination with the results of chemical analysis.
