- Abstract
The α-Afflb was coated with stearic acid (SA) by the method of solvent-nonsolvent. The crystal structure and the morphology of the prepared samples before and after coating were characterized by Fourier transform infrared spectroscopy (FTIR), elemental analysis (EA), scanning electron microscopy (SEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The electrostatic sensitivity of CC-AIH3 samples before and after coating was measured by JGY-50 III. The results show that coating agent is firmly coated on the surface of α-AIH3. The testing results show cc- AIH3 coated with SA can decrease the electrostatic sensitivity. The spark energy required for 50% initiation probability (E50) increased from 367 mJ to out of range.
