摘要：

Before investigating the growth of aluminium orthophosphate single crystals (berlinite) under hydrothermal conditions, we have studied AlPO4 solubility in phosphoric acid solutions, as a function of various parameters: temperature (150° to 550° C), pressure (up to 1400 bars), solvent concentration (5 M to 12 M). Our results are reported here and show that several hydrothermal techniques can be used for growing AlPO4 crystals: slow increasing the temperature of a saturated solution; growth in a reverse temperature gradient (T < 350° C); growth in a direct temperature gradient (T > 350° C and P > 1000 bars). © 1979.
