沉淀出凝胶的溶液的pH值决定了煅烧氧化锆晶相。单斜氧化锆是由在 6.5 至 10.4 pH 范围内沉淀的材料生产的；在3至4或13至14的pH范围内获得四方前体。煅烧气氛、煅烧过程中的温度历史以及碱的存在似乎在确定氧化锆相组成方面并不起主导作用。
The pH of the solution from which the gel is precipitated determines the calcined zirconia crystal phase. Monoclinic zirconia is produced from materials precipitated in the 6.5 to 10.4 pH range; the tetragonal precursor is obtained for the 3 to 4 or 13 to 14 pH range. The calcination atmosphere, temperature history during calcination, and the presence of alkali do not appear to play a dominant role in determining the zirconia phase composition.
