| titleOfInvention | Production of magnetite fine powder |
| abstract | PURPOSE: To obtain magnetite fine particles of submicron having particle size distribution with small variability industrially advantageously, by subjecting an iron carbonyl compound to gaseous-phase thermal decomposition in the presence of oxygen. n CONSTITUTION: Vapor of an iron carbonyl compound (e.g., iron pentacarbonyl) is sent to a reactor by an inert gas (e.g., carbon dioxide or argon), blended with oxygen, heated and thermally decomposed in a gaseous phase. Then, formed magnetite fine particles are gathered by a collector to give the aimed magnetite fine particles. The amount of oxygen blended is properly about 0.75W3.25mol based on 1mol iron, metallic iron is formed when the amount of oxygen is small and trivalent iron oxide such as hematite, etc., are formed when the amount is large. The reaction temperature is properly ≥about 300°C and too low temperature produces metallic iron as a by-product. n COPYRIGHT: (C)1987,JPO&Japio |
