초록
Langasite({{{{ { La}_{ 3} {Ga }_{5 } {SiO }_{14 } , LGS}}}}) powder was prepared by a polymerized complex method based on the Pechini-type reaction. A mixed solution of ethylene glycol(EG), cotric acid(CA), lanthanum, gallium and silicon ions, with a molar ratio of EG:CA:La:Ga:Si=100:25:3:5:1, was polymerzed to from a transparent resin, which was used as a precursor for the synthesis of LGS. X-ray diffraction(XRD) patterns indicated that the LGS phase could be formed by the heat-treatment in air at 1000
