Thermal and Combustion Properties of 3,4-Bis(3-nitrofurazan-4-yl)furoxan (DNTF)

摘要

Thermal decomposition of melted 3,4-bis(3-nitro-furazan-4-yl)furoxan (DNTF) in isothermal conditions was studied. The burning rates of DNTF were measured in the pressure interval of 0.1-15 MPa. The thermal stability of DNTF was found to be close to the stability of HMX, while the burning rate of DNTF was close to the burning rate of CL-20. The thermocouple measurements in the combustion wave of DNTF showed that combustion of DNTF was controlled by the gas-phase mechanism. The DNTF vapor pressure was determined from thermocouple measurements and agreed well with data obtained at low temperatures under isothermal conditions.
