The Detonation Properties Research on TKX‐50 in High Explosives

Abstract

Abstract The mechanical sensitivity of TKX‐50 under different preparation conditions and its preparation process to explosive samples were examined. The detonation properties of TKX‐50 based samples were determined. The results show that the column density can reach 1.80‐1.81 g cm −3 under the specific pressure of 3000. Different column diameters with different detonation velocities show the obvious scale effect of TKX‐50 based explosives. The critical initiation pressure of TKX‐50 based explosives is much higher than HMX and CL‐20 based explosives, which means a much lower shock sensitivity. The determined explosion heat value of TKX‐50 based explosiveis 4650 J g −1 , which is also much lower than HMX and CL‐20 based explosives.
