Optimized synthesis routes allowed preparing polycrystalline hydroxycarbonate La203_x(OH)y(C03)z and langasite La3Ga5Si014. Langasite precursor was used to form a first langasite polycrystalline thin film. The thermal stability of lanthanum hydroxycarbonates La203_x(OH)y(C03)z (noted LHC) resulting from surface hydration and carbonation of La203 was studied by Fourier Transform infrared spectroscopy and electrical impedance analysis. Piezoelectric oxide La3Ga5SiO|4 might be used as a piezoelectric substrate associated with catalytic LHC systems, in gas sensor devices
