(Mg1-xSrx)2Al4Si5O18陶瓷的显微结构与微波介电性能研究

摘要

(Mg1-xSrx)2Al4Si5O18 ceramics were fabricated by traditional ceramic sintering method. The phase transformation from β-Mg2Al4Si5O18 to α-Mg2Al4Si5O18 was accelerated and the width of sintering range was boarded due to Sr ions doping. The XRD patterns show that the cordierite solid solution of (Mg,Sr)2Al4Si5O18 is kept in the range of O≤x<0.2, and the feldspar solid solution of (Sr,Mg)Al2Si2O8 is kept in the range of 0.6
