| 摘 要： | Two kinds of high efficient Agl pyrotechnics BR-88-5 and BR-91-Y have been developed.The tests in the cloudchamber show that the AgI ice nucleating effectiveness can reach up to 10~(15)/g,and the BR-91-Y has even higher icenucleating rate.Two kinds of foreign AgI pyrotechnics have been made according to the given formulations and alsotested in the cloud chamber for comparison.X-ray diffraction analysis for the aerosols produced by burning BR-91-Yshows that AgI in acrosols still retains the hexagonal crystal form and the lattice parameters are smaller than those ofpure AgI and other AgI composite nuclei,and closer to ice.Combining with the other tests,the reasons for the high effi-ciency of BR-91-Y have been discussed.

| Abstract: | Two kinds of high efficient Agl pyrotechnics BR-88-5 and BR-91-Y have been developed.The tests in the cloud chamber show that the AgI ice nucleating effectiveness can reach up to 10~(15)/g,and the BR-91-Y has even higher ice nucleating rate.Two kinds of foreign AgI pyrotechnics have been made according to the given formulations and also tested in the cloud chamber for comparison.X-ray diffraction analysis for the aerosols produced by burning BR-91-Y shows that AgI in acrosols still retains the hexagonal crystal form and the lattice parameters are smaller than those of pure AgI and other AgI composite nuclei,and closer to ice.Combining with the other tests,the reasons for the high effi- ciency of BR-91-Y have been discussed. |
