Of A Al Ball Mill

Self propagating reaction induced by ball milling in a

The mechanochemical reduction of Cu 2 O with Al was induced via ball milling A self propagating reaction took place in two distinctly different ways If the mass of the reactant powder mixture was large enough ignition happened within a few seconds after starting the mill Neither the activation of the reactants nor the formation of a powder layer covering the surfaces of the milling tools

Reactivity Enhancement and Fabrication of Al MoO 3

The bond strength of the Al MoO 3 coating was however weaker than that of a pure Al coating because the MoO 3 powder interrupted the intimate bonding between the Al splats A reactivity analysis demonstrated that ball milling improved the reactivity of both the powders and the coatings by increasing the exothermic value decreasing the reaction onset temperature and decreasing the activation
