The upper limit of solid solution of <TEX>$Al_2O_3$</TEX> in <TEX>$LiTaO_3$</TEX> was investigated using X-ray diffraction and Raman spectroscopy. By substituting cations in <TEX>$LiTaO_3$</TEX> with <TEX>$Al^{3+}$</TEX>, the melting temperature was lowed and the ferroelectric properties can be improved. It is easier at lower temperature to fabricate the single crystal used for SAW filters and IR sensors. From the measured lattice constants and Raman band broadening, the solubility limit was X
