Theoretical Study of the Grinding and Homogenization of

2021-11-2 · Abstract A mathematical model in a macroscopic approximation is used to perform a theoretical study of solid-phase mechanochemical synthesis in a binary powder mixture during its mechanical processing in a mechanoactivator (energy-intensive mixer). Analytical relationships are obtained for the parameters that determine the process. The formulas are used to propose a way of

The strength of the inter-sublattice coupling in all samples is estimated by analyzing high-field magnetization data. In our work is shown that nitrogenation weakens the inter-sublattice exchange interaction in the compounds up to 45 - 50 %. Grinding time and, as a consequence, particle size affects the inter-sublattice exchange interaction.
