Silicon carbide (SiC) coatings and films have been prepared for the first time by electrostatic atomization of a solution of a polymeric precursor and deposition on to alumina and zirconia substrates. The deposits were heated to 13008C prior to their examination by X-ray energy-dispersive spectra and selected-area diffraction in scanning and transmission electron microscopes. The results show that these coatings and films are crystalline and probably consist of co-existing a- SiC and b-SiC phases.
We thank the Royal Society of the UK for funding electrostatic atomisation research at Queen Mary, University of London, by providing an equipment grant to Professor Edirisinghe and a visiting post-doctoral fellowship to Dr Grigoriev.
