Zusammenfassung:Attempts to measure adsorption on the surface of HMX using N2 and CO with the continuous flow modification of the BET gas adsorption technique were unsuccessful. Either (1) no adsorption takes place on the HMX under these conditions, (2) the gas adsorption technique is not sensitive enough to be used to measure the area of a surface as inactive as that of HMX, or (3) the adsorption which actually takes place is masked by effects due to heretofore unoberved polymorphic changes in the crystalline structure of the material. Heating the HMX crystals to about 185 C, well below the melting point, does not activate the surface, but results rather in amount of decomposition. (Author)
