Fabrication of Vanadium Sesquioxide Powder by Hydrolysis Method

School of Materials Science and Engineering, Henan University of Technology, Zhengzhou 450001, Henan, China

摘要: 通过水解硫酸氧钒,在不加入还原剂条件下合成了三氧化二钒粉体,研究不同烧结温度以及气氛对产物的影响;对产物进行X射线衍射分析、扫描电镜形貌观察和激光粒度仪粒度检测,结果表明:在不同的气氛中,以5℃/min的升温速度,由室温升至800℃并保温3 h得到的产物不同。在氩气流量为160 mL/min的气氛中得到V₄O₇粉体;而在真空中煅烧的产物是V₂O₃粉体,其在玛瑙研钵中研磨20 min平均直径为452 nm。确定了水解硫酸氧钒获得氢氧化钒沉淀的最佳pH值约为4。

Abstract: V₂O₃ powder was prepared by hydrolyzing VOSO₄ without adding reducing agent.The effects of atmosphere and temperature on the sintering behavior were studied.The products were analyzed by X-ray diffraction(XRD),scanning electron microscope(SEM) and laser particle size analyzer.The results show that different products are obtained with 5℃/min heating rate in different atmospheres from room temperature to 800℃ and with insulation for 3 h.The product is V₄O₇ powder in argon atmosphere with flow rate of 160 mL/min,while the V₂O₃ powder is obtained in vacuum,with average diameter of 452 nm after being grinded in agate mortar for 20 min.The optimum pH for vanadium hydroxide by hydrolyzing VOSO₄ is approximately 4.
