Elementary Research on Preparation of AlB12 Powder by Self-Propagating High-Temperature Synthesis (SHS)

Article Preview

Abstract:

The preparation of AlB12 powder by SHS has been investigated. Mg, Al2O3 and B2O3 powders were mixed as staring materials. SHS products were treated by acid pickling. Adiabatic temperatures were calculated by HSC software. XRD, SEM, TEM analyses were used products after acid picking treatment. The reason caused AlB12 low purity is the formation of Mg0.4Al2.4O4 and insoluble matter
