摘要： A process for producing a magnetic powder which comprises coating the particle surfaces of a magnetic iron oxide with a cobalt compound or a cobalt compound and a ferrous compound and further coating with a compound of at least one metal selected from the group consisting of manganese, vanadium and zinc. There is obtained a magnetic powder having high coercivity and excellent dispersibility in organic binders. This magnetic powder is useful as a material for recording media such as magnetic tapes.

摘要： Titanium oxide particles comprising particulate titanium oxide substrate having a zinc oxy compound or a combination of a zinc oxy compound and a silicon oxy compound supported thereon. They can be produced by adding a zinc compound or a combination of a zinc compound and a silicon compound together with an alkali to a dispersion of particulate titanium oxide substrate to neutralize the zinc compound or the combination of the zinc compound and the silicon compound in said dispersion, then separating and drying the resultant product. They are useful for pigments, catalysts, catalyst supports and adsorbents, and particularly excellent in deodorizing performance by removing malodorous gases such as ammonia, methyl mercaptan, hydrogen sulfide, trimethylamine, methyl sulfide and acetaldehyde through decomposition and adsorption thereof, so that they are useful as white deodorants for sanitary objects such as paper diaper and sanitary napkins which come to directly contact with the skins of human beings.

摘要： The present invention provides a process for producing magnetic metal powder for magnetic recording using a metal compound mainly composed of a hydrous iron oxide on an iron oxide, characterized in that prior to subjecting the metal compound mainly composed of a hydrous iron oxide or an iron oxide to a reduction treatment, addition of a boron compound and a heat treatment at 350.degree.-750.degree. C. in a gas atmosphere having a water vapor partial pressure of 10 mmHg or higher are carried out. When a heat treatment at 550.degree.-900.degree. C. in a non-reducing atmosphere is carried out in combination with the above heat treatment, the effect of the present invention is further increased.
