Carbon dioxide assisted nebulization with a bubble dryer (CAN-BD) was used to reformulate TATB, a notoriously insoluble material, into nanoparticles. The method is reproducible and produces particles consistently in the range of 100-400 nm with a mean of approx. 228 nm. Chemical analyses of the material do not indicate any decomposition or degradation of the TATB resulting from the process, and there does not appear to be any measurable amount of residual solvent or other impurities in the particles.
