Samples of berlinite (α-AlPO4) have been grown by slow heating method. The thermal behavior of elastic prepeties have been studied by transmission method from 30℃ to 150℃. The equations for the temperature behevior of elastic constants have been obtained by polynomial least square method and the 1st, 2nd and 3rd order temperature coefficients of the elastic constants have been calculated (T0=25℃).
