Influence of pH value and solvent utilized in the sol–gel synthesis on properties of derived ZrO2 powders

Effect of calcination temperature on the textural properties of 3mol% yttria-stabilized zirconia powders

“…The atomic arrangement is consequently more ordered and the porosity and surface area decrease markedly. A similar behavior has been previously described in the literature by Caruso et al [1] and Caracoche et al [3]. Table 1 S BET = specific surface area; V mi = micropore volume; V me = mesopore volume; D = Fractal dimension; n.a.…”

“…It is not surprising therefore that the ceramic materials have received a great deal of attention in the last few decades [1][2][3][4]. One of the most commonly used methods for the synthesis of zirconia-based powders appear to be those using liquid precursors and, in particular, the sol-gel method [5].…”

A comparative study of the pressureless sinterability of 3 mol% Y 2 O 3 -stabilized ZrO 2 powders prepared by the sol–gel method under different synthesis conditions without modifiers

“…In the temperature range 300-450 1C one can see a continuous mass loss in the TG curve, together with two exothermic peaks that are caused by the elimination of the bound water and organics [12,13]. At $ 460 1C, an exothermic peak appeared in the DTA curve without mass loss in the TG curve, which has been reported as being due to the crystallization of the ZrO 2 [14]. Taken together, the elementary analysis of carbon and the DTA-TG analyses indicate that the crystallization of the 3YSZ powders only occurs after the calcination-induced elimination of the residual of the sol-gel synthesis [15].…”

A novel strategy for the preparation of yttria-stabilized zirconia powders

“…In fact, zirconia-based ceramics constitute a group of highly demanded materials [3,4]. In the last few years a number of papers have been published in connection with the use of zirconia as the starting material for the preparation of new ceramics [5][6][7][8][9].…”
