METHOD FOR PRODUCING MAGNETIC FLUID CONCENTRATE Russian patent published in 1994 - IPC

Abstract RU 2016430 C1

FIELD: processes. SUBSTANCE: magnetic concentrate is produced from a suspension produced by partial air oxidation of an iron salt of etching solutions of metallurgic productions. The obtained highly dispersed magnetite is stabilized by a hydrophobic stabilizer. The magnetic concentrate is used for producing magnetic fluids on different bases. EFFECT: simplified processing and convenience of transportation. 1 tbl
