Preparation and Microstructure of CaZrO₃ Materials

Resources Engineering School, UST Beijing, Beijing 100083, China

摘要: CaZrO₃在CaO-ZrO₂體系化合物中CaO含量最高且最穩定的一種化合物.利用CaCO₃和m-ZrO₂為原料在1450℃預先合成后又于1600℃重燒,其CaZrO₃晶粒發育更加完善.利用這種方法合成的CaZrO₃為原料,不添加助燒劑在1700℃時就可以獲得接近理論密度的燒結體,其顯微結構特征是CaZrO₃顆粒緊密堆積,而且晶形發育極其良好.

Abstract: CaZrO₃ containing the highest CaO colltellt of compounds in system CaO-ZrO₂ is a potential refractory material. A satisfactory CaZrO₃ raw material as formed from equimolar proportions of CaCO₃ and ZrO₂ subjected to two-stage synthesis:preparing first at 1450℃ and then refiring to 1 600℃. A close approach to theoretical density specimen was obtained with finely ground the raw material at 1700℃ sintering. By SEM the grains of CaZrO₃ with perfect morphology was found to be linking closely in it.
