The history and tueoretical basis of the Becker-Kistia, kowsky-Wilson (BKW) equation of state are reviewed, and the results of an extensive parameter study are described. The covolumes of water and carbon dioxide were changed to 250 and 600, respectively, to obtain better agreement with the experimental Hugoniots. Using these covolumes, a single set of BKW equation-of-state parameters could not be found that would reproduce the experimental detonation properties of TNT and RDX within experimental error. The BKW equation-of-state parameters tuat would reproduce the detonation velocity-density curve of RDX from 1.8 to 1.0 g/cc were found to result in a physically unrealistic hehavior above 0.5 megabar. It was found that tue BKW equation-of-state parameters alpha = 0.5, B = 0.16, and K = 10.91 were satisfactory for most explosive systems and that alpha = 0.5, BETA = 0.09585, x = 12.685 were satisfactory for high- density explosives whose detonation products contain large amounts of solid carbon. The computed detonation properties using tuese equation-of-state parameters and covolumes are preserted for several explosives. (auth)
