Resumo

Fine Ti powders were prepared through magnesiothermic reduction in TiO₂–Mg–Ca mixtures under 4 MPa of Ar followed by acid leaching (with HCl or HNO₃) and characterized by XRD, SEM/EDS, and chemical analysis. Thus prepared Ti powders exhibited the specific surface ranging between 7.0 and 30.0 m²/g. The produced Ti powders can find their application in pyrotechnics, powder metallurgy, and as raw material for SHS of inorganic compounds.
