| titleOfInvention | Granules for magnetic iron oxide particles for magnetic recording, method for producing the same, and method for producing magnetic iron oxide particles for magnetic recording using the granules |
| abstract | (57) [Summary] (Modified) [Purpose] Granules for magnetic recording magnetic iron oxide particles and acicular granules comprising acicular hydrous ferric oxide granules or acicular ferric oxide granules Providing a manufacturing method for industrially obtaining products. [Structure] Semi-synthetic starch or semi-synthetic cellulose soluble in water or warm water is added to a suspension obtained by suspending acicular hydrous ferric oxide particles or acicular ferric oxide particles in water. After adding 0.1 to 5.0% by weight to ferric oxide particles or acicular ferric oxide particles and stirring, the cake obtained by compression dehydration is granulated to obtain the average particle size. Is 1 to 7 mm, the bulk density is 0.3 g / cm 3 or more, and the pulverization rate is 40% or less. After obtaining a granule for magnetic iron oxide particles for magnetic recording, the granulation is performed. The substance is heated and reduced in a reducing gas to obtain needle-shaped magnetite particles, or further oxidized to obtain needle-shaped maghemite particles. Alternatively, it is modified with Co and Fe 2+ to obtain magnetic iron oxide particle powder for magnetic recording. |
