However, its poor sinter ability requires the use of sintering aids for its processing. The sintering behaviour of three different SnO2-based powder mixtures, containing Bi2O3 in amounts between 1 and 2mol%, has been analyzed. The effects of thermal treatment parameters (heating rate, maximum temperature and soaking time) on the densification were obtained by a factorial experimental design 23. Bi2O3 adequate proportion (around 1.5%) combined with a fast heating (15°Cmin−1) and a high maximum temperature (1300°C), allows reaching densifications around 45%. However, soaking time has no significant effect over densification. An interpretation of the significant effects has been proposed based on thermodynamic behaviour of Bi-containing compounds and the mass transport mechanisms. ER -
