Hematite and hematite-akageneite composites were obtained by hydrolysis of FeCI3 in acidic medium. The IEP of hematite and of hematite-akageneite composites was at pH about 9. The particle radius of primary hematite particles was about 50 nm and the primary particles of hematite-akageneite composites were larger and porous. Addition of SDS to dispersions containing hematite or hematite-akageneite composites resulted in substantial increase in the particle size. (C) 2015 Elsevier Inc. All rights reserved.
