以电熔ZrO2粉和活性石灰粉为原料,研究了不同成型压力对合成CaZrO3的影响,并利用XRD和SEM对材料的矿物相和微观结构进行了分析。实验结果表明:随着成型压力的增加,试样的致密程度加大;当成型压力达到200 MPa后,成型压力对合成锆酸钙材料的致密度影响减弱。成型压力对合成锆酸钙材料的矿物相无影响,对材料的显微结构影响甚微。综合分析,适宜的成型压力为200 MPa。
以電鎔ZrO2粉和活性石灰粉為原料,研究瞭不同成型壓力對閤成CaZrO3的影響,併利用XRD和SEM對材料的礦物相和微觀結構進行瞭分析。實驗結果錶明:隨著成型壓力的增加,試樣的緻密程度加大;噹成型壓力達到200 MPa後,成型壓力對閤成鋯痠鈣材料的緻密度影響減弱。成型壓力對閤成鋯痠鈣材料的礦物相無影響,對材料的顯微結構影響甚微。綜閤分析,適宜的成型壓力為200 MPa。

This paper studies the impact of forming pressure to performances of synthesized CaZrO 3 , which is made of fused zirconia powder and active lime powder as raw materials ,and analyses the mineral facies and microstructure by XRD and SEM .The results show that density increases with the forming pressure going up;when the pressure reaches up to 200MPa,its effect on density becomes weak;the pressure has no effect on mineral facies and little effect on microstructure .In conclusion , the optimal forming pressure value is 200MPa.
