摘要
简述了硝酸钡的应用前景及国内外生产技术现状，论述了以硫化钡和硝酸铵为原料复分解法制硝酸钡的工艺流程及反应机理。试验结果表明，新工艺可获得符合国家标准ＧＢ－１６１３－７９一级品硝酸钡产品，产品收率在９８％以上，有较好的经济效益。
The current situation in technics and prospect in application of barium nitrate are summarized. The technological process and action mechanism of preparing barium nitrate by the double decomposition using ammonium nitrate and barium sulfide as the raw materials are described. The test results indicate that the products come up to first grade of the national standard GB 1613 79 and the recovery more than 98%, being of a good economic benefit.
