Sublimation studies of hexanitroazobenzene (HNAB), Sandia Lot 43-11-B, have shown all sublimation residues to be essentially HNAB (form 3), with HNAB (form 2) found in the sublimates. The sublimation condensate in the lower temperature ranges (80--130 C) has a non nitro group material, and an HNAB like (nitro group) material was found in the 160--190 C condensates. The presence of aliphatic impurity(s) in all fractions, from 80 to 220 C, has been determined albeit the concentration decreases significantly at the higher temperature ranges (200--220 C)
