摘要
利用IR光谱和Raman光谱等实验手段,对25℃时Rb2Ca[B4O5(OH)4]2·8H2O的溶解及相转化过程进行了初步探索,结果表明,Rb2Ca[B4O5(OH)4]2·8H2O溶于水后,硼在溶液中主要以B(OH)3和[B(OH)4]-的形式存在,残留固相由开始的无定形水合三硼酸钙,最终部分转变为Ca2[B3O3(OH)5]2·8H2O晶体。
The preliminary studies on the dissolution and transformation of Rb_2Ca_2·8H_2O were carried out by using IR spectroscopy,Raman spectroscopy,and other experimental methods.It is indicated that the tatraborate anion is depolymerized to B(OH)_3 and ^- during the dissolution process.Some amorphous residue will be transformed into the crystal hydrated calcium triborate.
