    • Ammunition rim fire priming mixtures are commonly prepared by mixing normal lead styphnate, a sensitizer, such as tetracene, an oxygen donor such as lead nitrate, and a frictionator such as ground glass. This invention relates to such a mixture and to center fire priming mixtures which consist of lead styphnate, tetracene, inorganic fuels and barium nitrate and to a method of forming them and is characterized by the use of lead styphnate which is formed in situ by the reaction of a water wet mixture of styphnic acid and a lead compound such as lead oxide (litharge), lead hydroxide, basic lead carbonate, or lead carbonate. The lead styphnate which results from the practice of this method has been isolated and subjected to X-Ray diffraction analysis confirming that this is a novel form of lead styphnate and is indeed a new compound. Important advantages of this invention are reduced cost, improved safety since it is unnecessary to prepare, precipitate, or separately handle pure or relatively pure lead styphnate and because the wet mixtures are insensitive, and improved percussion sensitivity of the resulting mixtures when dried for use.
    • 弹药边缘起火混合物通常通过混合正常的铅前列素,敏化剂如并四苯,氧供体(如硝酸铅)和摩擦剂如研磨玻璃来制备。 本发明涉及这样一种混合物,并且包括由苯磺酸铅,并四苯,无机燃料和硝酸钡组成的起火混合物以及形成它们的方法,其特征在于使用由反应原位形成的邻苯二甲酸铅 的硫酸和铅化合物如氧化铅(锂),氢氧化铅,碱式碳酸铅或碳酸铅的水湿混合物。 由该方法的实践产生的铅链霉菌已经被分离并进行X射线衍射分析,证实这是一种新型的铅酸铅,并且确实是一种新的化合物。 本发明的重要优点是降低了成本,提高了安全性,因为不需要制备,沉淀或分开处理纯的或相对纯的铅酸铅,并且因为湿混合物不敏感,并且当干燥使用时,所得混合物的冲击灵敏度得到改善。
