Abstract
Cr1 − xTixO3+x/2, with x = 0.05,0.1 and 0.2, powders have been synthesised by an emulsion gelation route starting from aqueous chloride solutions. Gel particles were produced by de-anionisation of a water-in-oil emulsion using an immiscible organic amine solution. After calcination to produce the oxide, the powders were characterised in terms of particle size distribution, crystallinity, surface composition, particle shape, surface area, anion contamination and doping uniformity. By optimising the processing variables it has been possible to produce un-agglomerated, spherical, uniformly doped powders with a narrow particle size distribution. The mean particle size can be controlled within the range 0.3 to 3 microns and the particles are porous and nano-crystalline. The powders have been used to fabricate thick film sensor structures and show good response to combustible gases in air.
