Single crystals of BaSO4 and SrSO4 up to 2 mm in length have been grown in silica gels and identified. The progressive deterioration in crystal quality with the increasing size observed in the present work has been studied and is attributed to the incorporation of gel during growth. The amount of gel inclusion is found to increase with the increasing size of the crystal producing opaque and poorly faceted crystals. The effect of temperature on the crystal morphology has been studied. It is observed that at a temperature of 35°C, crystals with {011} and {120} habit faces grow, while at about 20°C additional {001} faces appear. Also, interpenetrating twinning of these crystals occur at this temperature.
