Abstract
Langasite is a new piezoelectric material which is similar to quartz in its acoustic behaviours. In this study, pure Langasite and Langasite family grouo powders were synthesized by the solid state reaction in air. And then diffusion of synthesized powders were controlled by B and C ions in the{{{{ { A}_{ 3} { B}_{5} { CD}_{ 14 }}}}} structure. Dielectric constant and lattice anisotripy of Langasite and family group were measured to be 17, 22~27 in the range of 1 kHz to 13 MHz and about 1.6. respectively.
