| Abstract: | To improve the storage stability of potassium borohydride(KBH4), sodium borohydride(NaBH4) and lithium aluminum hydride(LiAlH4), KBH4 and NaBH4 were coated by paraffin via solvent-nonsolvent method and LiAlH4 was coated by naphthalene via recrystallization. The surface coating stafas of the samples was studied by SEM, FTIR and XRD and the combustion properties of the propellants added into coated sample were tested by an Infrared Thermometer. Results show that KBH4, NaBH4 and LiAlH4 are completely coated and the coating stafas of NaBH4 is the best. The combustion properties of propellant added with coating-NaBH4 sample are significantly improved and the burning rate is increased by more than 5%. |
