摘　　要：研究了添加ＣａＯ对Ｃａ０．５Ｚｒ２（ＰＯ４）３（ＣＺＰ）晶格热膨胀特性及宏观热膨胀的影响。Ｃａ２＋离子进入ＣＺＰ晶格造成热膨胀各向异性低温下增大高温下减小，宏观热膨胀系数近似呈线性影响。Abstract The influence of CaO on axial thermal expansion characteristics and coefficient of thermal expansion of Ca_0.5Zr_2(PO_4)_3 (CZP) was studied. The Ca^2+ ions coming into lattice of CZP results in thermal expansion anisotropy of CZP increasing at low temperature and reduing at high temperature. The coefficient of thermal expansion of CZP by dilatometry linear increases with the increase of CaO content.ail)
