TACOT tentatively named tetranitrodibenzo1,3a,4,6a-tetrazapentaline, and TATB 1,3,5triamino-2,4,6-trinitrobenzene have the lowest thermal decomposition rates of a series of heat resistant explosives compared by means of 2-hr exposures to 260 and 280 C. The order of resistance of small quantities to rapid, complete decomposition on sudden exposure to temperatures above 300 C is TATB, TACOT, and DATB 1,3diamino-2,4,6-trinitrobenzene. TACOT is more easily initiated by explosive shock than DATB and is considerably easier to initiate than TATB. TACOT and DATB have similar detonation properties preliminary data indicate that the plate push velocity of TACOT is 5 to 10 percent lower than that of DATB. Solvent pressing considerably improves the density of TACOT charges and preejection cooling reduces mechanical failures. The maximum attainable pressed density for the present form of TACOT appears to be about 95 theoretical maximum density.
