| 摘 要： | 采用氢氧化钾熔融法以不同无机酸处理合成了铌酸。利用傅立叶变换红外光谱仪,热重分析仪和紫外-可见-近红外光谱仪对合成的铌酸分别进行了表征。结果表明,经冰醋酸处理合成的铌酸纯度较高,用硫酸和硝酸处理合成的铌酸含有少量杂质,而磷酸处理后没有得到铌酸。

| Abstract: | Niobium acid was synthesized by potassium hydroxide melting method using different inorganic acid treatment and its properties were characterized by FF-IR, TG and UV-VIS spectra. The results showed that niobium acid synthesized by acetic acid treatment was of high purity, and synthesized by sul- furic acid and nitric acid treatment contained small amount of impurities. Niobium acid was not obtained by using phosphoric acid treatment. |
