SEM image of the Manta's magnetite nanoparticles. Early in our company's history we searched for a cost-effective source of magnetite nanoparticles for our renewable fuel production process. Frustrated at the lack of cost-effective products in the marketplace, we developed our own low-cost, high purity nano-magnetite production process.

Magnetite (composition Fe3O4) has a specific gravity ranging from 5.0 to 5.1, and is sufficiently heavy to permit of its concentration from gangue by specific-gravity methods, which have had an extensive application. The object of the separation, however, is twofold: the concentration of the mineral in the raw ore to a product of sufficient ...

Plastic molding is accomplished by extrusion, jiggering, or powder injection molding. Extrusion is used in manufacturing structural clay products and some refractory products. Jiggering is widely used in the manufacture of small, simple, axially symmetrical whiteware ceramic such as cookware, fine china, and electrical porcelain.

A process for producing single phase magnetite powder, comprising adding 0.1 to 4.0% by weight of a liquid or powdered substance having a carbon-to-carbon single or double bond to hematite powder, stirring the mixture to obtain a substantially homogeneous mixture, and heating the mixture in an inert gas at 1200° to 1450° C. wherein, after ...
