Explosive performance of HMX/NTO co-crystal
A new co-crystal explosive of 1,3,5,7-tetranitro-1,3,5,7-tetrazocane(HMX)and 3-nitro-1,2,4-triazol-5-one(NTO)in a molar ratio of 1:1 has been prepared by solvent/antisolvent method.The SEM photographs show that HMX/NTO co-crystals are distinctly different from HMX and NTO crystals.The co-crystals are prisms with well formed crystal surfaces.Thermal analysis results indicate the melting point of the co-crystal is 29.3℃higher than that of NTO.Moreover,the co-crystal exhibits a modified mechanical sensitivity.The characteristic height(H50)of impact sensitivity increases 14.8cm,and the explosion percentage(P)of friction sensitivity decreases by 40%compared with HMX.The HMX/NTO co-crystals possess good thermal property and low sensitivity,which mean huge advantages in blasting engineering.
