The heat output is determined using high speed pyrometry for various powders under shock loading in the present work. The pyrometry data for copper and silica powders obtained earlier are complemented with data for an iron powder. Comparison of the data for the three powders shows an unusual high heat output for the iron powder. However, the two-phase constitutive CTH modelling reveals a possible reason for this higher output which could be the larger particle size. Calculations for powders with similar particle sizes demonstrate that the heat output for the iron powder lies between that for the copper and silica powders, which agrees with the inter-phase heat fluxes substantiated by the thermo-physical properties of the condensed constituents.
