Abstract
THE great solubility of silver iodide in concentrated potassium iodide solution and the rapid decrease of this solubility on dilution with water suggested that single crystals of silver iodide could be grown by a gel method1 similar to that used for growing crystals of cuprous chloride2. Indeed, small silver iodide single crystals have been grown from solution by a dilution method. They appear as hexagonal prisms up to 20 mm in length and 2 mm in diameter or hexagonal pyramids up to 3 mm long and 1.5 mm across the base and take about 6–8 weeks to reach this size3. It seemed plausible that a combination of the two methods would yield larger and better crystals.
