Conventional sintering heating elements

It can be seen in fig. 4 that the presence of the doping element increase the surface area of the zirconia compound as well as its textural stability. Specific surface areas above 200 m /g can be obtained., twice higher than those from conventional preparations under similar heat treatments (500°C). The values of surface areas determined by nitrogen adsorption are close to those calculated ffom the crystallite sizes of XRD patterns and according to the assumptions made in ref [7]. Under thermal treatment crystallite growth is not intense but inter-crystallite sintering occurs in the case of V, Nb and Cr dopants and consequently a strong decrease in the specific surface area is observed. [Pg.278]
