Manganese complexes of various monovalent and divalent polyether antibiotics are provided which act as coccidiostats and growth promoting agents when administered to food-producing animals such as cattle, sheep, swine and poultry. Soluble manganese salt is added to a fermentation beer containing the polyether antibiotics to form an insoluble, recoverable biomass containing the desired manganese antibiotic complex. This biomass, in a dried form, can be given orally to animals such as cattle, shee...

Disclosed are manganese and copper-containing compositions comprising: (A) a manganese containing compound and (B) a copper containing compound, wherein said composition contains from about 0.05 up to about 23 g-atoms of manganese for each g-atom of copper in said composition. Also disclosed are fuel compositions and additive concentrates containing said manganese and copper-containing compositions. Additionally, disclosed is a method for reducing ignition temperature of exhaust particulate from...

Method for the reactive dehydration of manganese dioxide. Dehydration is achieved by contact with a fluid desiccant (dehydrating agent) which reacts with water bound to manganese dioxide. Preferably, a gaseous product or a low boiling point liquid which easily produces vapors is formed. The manganese dioxide is then removed from the fluid desiccant and any adhering dessicant fluid and volatile reaction products are removed from the manganese dioxide under vacuum. Especially preferred for use as ...

Manganese vanadium oxides are used as pigments. The mnanganese vanadium oxide pigments are of the formula Mn.sub.2 V.sub.2 O.sub.7. The, pigments are useful as colorants, and also possess improved reflectance characteristics in the infrared region, thereby reducing IR-induced heat buildup.

Manganese dioxide having high bulk density, high tap density and high activity for use in batteries can be obtained by decomposing an aqueous solution of ammonia complex of manganese at a temperature of 68.degree. C. or higher than roasting the resulting manganese carbonate in an atmosphere of oxygen and 15-85% of steam at a temperature of 275.degree. to 375.degree. C.

Oxygen deficient manganese compounds of the formula CaMnO.sub.2.5 and Ca.sub.2 MnO.sub.3.5 have been prepared by the relatively low temperature reduction of precursors having the formula CaMnO.sub.3 and Ca.sub.2 MnO.sub.4, respectively. These compounds have a perovskite-type structure and are useful in processes requiring solid oxidizing agents, such as oxidative dehydrogenation processes.

Fine grained austenite achieved in (12%) manganese steel, without annealing, by a novel combination of carbon and aluminum.

A process for preparing an iron-manganese colorant, from an aqueous media containing metal ions, having an effective amount of iron and manganese present to impart color to building materials is disclosed.

A manganese dry battery includes an anode zinc can made of a zinc alloy containing 0.001-0.5 wt. % of titanium and at least one element selected from the group consisting of 0.001-0.05 wt. % of indium and 0.001-0.05 wt. % of bismuth, or a zinc alloy further containing 0.01-0.4 wt. % of lead. Even without heavy metals such as Hg and Cd, the zinc alloy anode can has a corrosion-resistant property and mechanical strength equivalent to or greater than those of the conventional zinc anode can, thereb...

The invention relates to the manufacture of manganese dioxide by a chemical process. The resulting product takes the form of gamma manganese dioxide particles characterized by filament-like protrusions of ramsdellite manganese dioxide jutting out from the surface of the particles. The manganese dioxide particles having such features can be manufactured by reacting manganese sulfate with sodium peroxodisulfate in an aqueous solution. The process can be controlled to yield high density manganese d...
