Patent number: 11158784Abstract: The present invention makes clear and defines a congruent composition of a langasite-based oxide, and establishes a method of manufacturing a crystal by any desired composition of AE3ME1+a(Ga1?xAlx)3+bSi2+cO14 (AE is an alkaline-earth metal, ME is Nb or Ta, 0?x?1, ?0.5<a?0 or 0<a<0.5, ?0.5<b?0 or 0<b?0.5, and ?0.5<c?0 or 0<c<0.5, excluding a=b=c=0). This makes it possible to suppress the formation of an impurity, and improve the yield and crystal manufacturing rate. The raw material is a raw material mixture prepared by mixing an alkaline-earth metal or its carbonate or oxide, Nb or Ta or its oxide, Ga or its oxide, Al or its oxide, and Si or its oxide.Type: GrantFiled: February 24, 2017Date of Patent: October 26, 2021Assignees: PIEZO STUDIO INC., TOHOKU UNIVERSITYInventors: Akira Yoshikawa, Yuui Yokota, Yuji Ohashi, Kei Kamada, Tetsuo Kudo, Kenji Inoue, Yasuhiro Shoji, Yu Igarashi, Mototaka Arakawa, Shunsuke Kurosawa, Akihiro Yamaji
