A method, articles and compositions are described for the direct addition of manganese metal to molten aluminum, which provide more rapid dissolution of the manganese in the aluminum than has been possible heretofore. The manganese is added to the molten aluminum in powder form (minus 14 mesh) in intimate admixture with a flux capable of forming a molten phase at the temperature of the molten aluminum to which the mixture is added. The flux, which is employed in an amount from about 3 to about 1...

This invention relates to manganese steels, in particular the invention relates to high strength iron-manganese based maraging-type steel combining high strength and toughness. Specifically, a manganese steel in accordance with the invention contains, apart from impurities, 11.8-13.5% by weight manganese, 2.0-6.0% by weight molybdenum, 0.002-0.2% by weight carbon, and optionally one or more of silicon (up to 0.4% by weight), sulphur (up to 0.02% by weight), and phosphorus (up to 0.03% by weight)...

Manganese byproducts produced in the course of manufacturing electrolytic manganese dioxide provide a novel manganese fertilizer having a fertilizer response that can operate both instantaneously and slow-release. A manganese fertilizer contains manganese byproducts and has 3 to 20 wt % citric acid-soluble manganese (C--MnO) and 0.5 to 7.0 wt % water-soluble manganese (W--MnO).

Austenitic (Hadfield) manganese steel containing about 25% manganese, 1.4% carbon and 0.1 to 1% silicon, balance essentially iron.

A method of manufacturing a manganese steel which comprises the steps of subjecting an alloy having the following composition by weight: carbon 0.9 to 1.4%; manganese 3.0 to 8.0%; chromium 1.0 to 2.5%; molybdenum 0.5 to 2.5%; silicon 0.25 to 2.0%; cobalt 1.0 to 5.0%; with the balance iron plus incidental impurities, to heating at a temperature within the range 900.degree. to 1100.degree. C. and then cooling the alloy to a temperature below 200.degree. C. to produce a wear-resistant manganese ste...

Aqueous ammoniacal solutions of divalent manganese, citric acid, and anti-oxidant provide soluble manganese in liquid fertilizers.

A homogeneous manganese dioxide composition having on a microscopic scale domains of alpha and delta manganese dioxide is manufactured by reacting a manganese-oxygen containing composition with a sodium containing composition at elevated temperature followed by acid treatment.

This invention relates to a novel crystal form of the 1:1 manganese (III) complex of N,N',N''tris[salicylideneaminoethyl]amine, a process for its preparation and the use thereof.

A lithium dioxide cell construction including a resettable positive temperature coefficient fuse. The positive temperature coefficient fuse, can withstand shock and mechanical vibration without damage and is mounted in such a way that it cannot be bypassed without destroying the cell. If the cell is shorted out, within a few seconds, the positive temperature coefficient fuse limits the fault current to a low value, which will never allow the cell to overheat or vent.

A manganese dry battery with excellent leak-proof property is provided, in which electrolyte leakage does not occur even if the size of a positive electrode material mixture is increased to meet a demand for improvement in discharge property. In a sealing part, a first circular projection, a second circular projection and a third circular projection are arranged at the bottom in sequence from the center to the outside, and a positive electrode carbon rod supporting part is provided in an innermo...
