Abstract: Electrical joint compounds for the protection of electrical connections are formed from a solution of polymer dissolved in solvent with or without conductive filler. Partially cured thermosetting polymers are preferred as they flow under service conditions to better seal the electrical joints. Thermosetting polymers which cure by an addition mechanism are preferred over those which cure by condensation, and polyimides are most preferred.

Abstract: Disclosed is a process for refining magnesium crude containing between about 0.7 and 1.5 wt. % calcium. The process includes mixing a flux containing from about 55 to 85 wt. % magnesium chloride and 45 to 15 wt. % alkali chlorides into a molten body of the crude. Refined magnesium is thereby produced, as well as a sludge containing calcium chloride which never has a liquidus exceeding the temperature of the molten body. The refined magnesium is then separated from the sludge.
