SUMMARY The ultrastructural localization of Ti in chemically modified chrysotile fibres has been studied. TiCl 3 ‐treated fibres were analysed by electron energy‐loss spectroscopy and electron spectroscopic imaging (ESI) along directions parallel and perpendicular to the fibre axis. ESI of ultrathin sections of conventionally embedded chrysotile fibres was made possible with the use of a cryo‐stage. The ESI images observed in fibre cross‐sections revealed that the Ti is located not only at the surface of the fibres but also inside the fibril tubes. This combination of microanalysis and imaging in the analytical electron microscope is the most suitable technique for relating the microchemistry and microstructure on a submicrometre scale.
