This final report, which covers the period from March 1972 to 30 June 1975, discusses some conditions for the synthesis of aluminum nitride AIN single crystals from solution. The solvent systems used are unique and novel. The average sized, water-white, bipyramidal AIN single crystals reproducibly grown from solution only were 1.1 mm long X 0.3 mm wide. The average sized, AIN single crystals grown from a combined solution-vapor reaction technique were 4mm long X 3 mm wide X 2mm thick. The in-house quantitative evaluation of the crystals was restricted to Laue patterns and emission spectrometry only. In Appendices A, B, C, and D, general discussions of solution growth, other AIN growth methods, some properties of AIN, and a very brief discussion of the newly emerging surface acoustic wave SAW device technology and why the use of AIN is considered a good electro-acoutic material in SAW devices are presented.
