Abstract [en]

Colloidal hematite particles with a diameter of about 130nm have been synthesized by forced hydrolysis using ferric chloride as a source material. Thin films of these particles have been deposited on alpha alumina substrates by a simple spin coating method. The deposited films were sintered at 800ÂșC with time varying from 1 minute to 6 hours. The influence of different heating times on the size and morphology of hematite particles were investigated. The films were characterized by X-ray diffraction and scanning electron microscopy after and prior to heating. The results show that the hematite particles grow from about 130nm to about 300nm after a total heating time of 6hrs. This work shows that these well defined hematite films are suitable model systems for sintering studies.
