Effect Of Particle Size And Particle Size Distribution On The Burning Rate Of Barium Chromate-Boron Pyrotechnic Delay Compositions, Donald J. Freeman

Theses

The burning rate of barium chromate-boron delay compositions is shown to be related to the 10 percent particle size point on the particle size distribution curve (particle size vs. percent greater than size) for either of the components. The burning rate is also shown to be inversely proportional to the 10 percent point of the barium chromate; and to follow a hyperbolic type relationship with the 10 percent of the boron, decreasing asymptotically as the 10 percent point increases. No correlations were found between the burning rate of the compositions and the average particle diameter, the mean particle diameter, or …
