Inorganic Materials Aims and scope

Abstract

This work demonstrates the possibility of predicting effective mechanical activation conditions for loparite concentrate from X-ray diffraction data with the aim of accelerating subsequent nitric acid leaching. We have calculated the enthalpy of formation, lattice energy, and atomization energy of loparite, a rare-earth titanate niobate.
