Mączka, Edward | Kosmulski, Marek
Hematite and hematite–akageneite composites were obtained by hydrolysis of FeCl3 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 50nm 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.
