The application is directed towards methods for purifying an aluminum feedstock material. A method provides: (a) feeding an aluminum feedstock into a cell (b) directing an electric current into an anode through an electrolyte and into a cathode, wherein the anode comprises an elongate vertical anode, and wherein the cathode comprises an elongate vertical cathode, wherein the anode and cathode are configured to extend into the electrolyte zone, such that within the electrolyte zone the anode and cathode are configured with an anode-cathode overlap and an anode-cathode distance; and producing some purified aluminum product from the aluminum feedstock.

Systems and methods for purifying aluminum

An apparatus, comprising: a substrate configured into a casing, a propellant configured between a projectile positioned/configured within the casing and an end of the casing, the propellant configured to expand upon a firing event and project the projectile from the casing; and a coating comprising a conformal coating layer having a particulate boron nitride dispersed therein, wherein the coating is configured to cover at least one of the inner sidewall and the outer sidewall, such that at least one side of the substrate is covered by the coating.
