Effect of the particle size on the burning behavior of B/KNO3 ignitor mixtures

Gun propellants and particularly LOVA-ammunition with low temp. sensitivity need matched ignitor systems of guarantee reliable and effective ignition. For this systems privileged conditions of the ignitor jet are only partly known like temp., particles and gas content. Also the influence of the mixt. prepn. like particle sizes and densities are less investigated. First approaches to investigate these influences to the burning behavior and ignitor jet of B/KNO3-mixts. and black powder are presented.
