Abstract Fine tin dioxide powders were prepared by a precipitation procedure from sulphuric acid solution. The influence of calcination temperature, aging and tin monoxide addition on the compaction behaviour and the sinterability of these SnO 2 powders were studied. The presence of SnO leads to an increase of green ceramic densities and favours densification during sintering. So pure SnO 2 ceramics with relative densities between 0.40 and 0.64 can be obtained by use of SnO 2 SnO mixtures as starting materials and of special temperature and atmosphere programs for the sintering process.
