Self-propagating high-temperature synthesis (SHS) process is used to prepare AlB12. The phase analysis results of preparing AlB12 with Al and B2O3 as raw materials show that: under air and argon conditions, the self-propagating and acid-washed self-propagating powders all have α-Al2O3 impurities; Mg, Al and B2O3 are used as raw materials. The phase analysis results of the preparation of AlB12 show that under argon conditions, the self-propagating and acid-washed self-propagating powder has unremovable MgAl2O4 impurities; the root cause of the low purity of AlB12 prepared by the self-propagating method is that there are unremovable impurities exist.
