摘　　要：采用共沉淀法在硼/铬酸钡延期药中加入一定量的缓燃氧化剂硫酸钡取代部分铬酸钡,制成硼/硫酸钡/铬酸钡延期药,利用光电转换原理测其燃烧时间,考察其延期时间与延期精度。结果表明:硫酸钡可以幅改变硼/铬酸钡延期药燃烧速度,硼/硫酸钡/铬酸钡延期药燃速稳定,延期精度高。Another oxidant BaSO4 has been added to a kind of delay composition containing B and BaGrO4 through coprecipitation method,instead of part of BaGrO4.The burning time of B/BaSO4/BaGrO4 delay composition can be obtain by Opti-Electronic Transformation,so the delay time and its precision is inspected.The result shows that the burning rate of B/BaGrO4 delay composition is changed largely because of BaSO4,and B/BaSO4/BaGrO4 delay composition has stable burning rate,high delay precision.
