Abstract

A novel hollow ceramic micro-fibre has a wall thickness of 0.01-15 (preferably 0.3-6, especially 0.5-3) microns and an outside diameter of 0.5-35 (preferably 1-25, especially 1-10) microns. Also claimed is a process for producing hollow micro-fibres, especially the above fibres, by (a) forming green hollow micro-fibres from a dispersion containing a ceramic precursor material and a thermally removable binder; and (b) removing the binder optionally using heat. Preferably, the ceramic is an oxide, silicate, nitride and/or carbide ceramic material.
