Abstract
Single crystals and powders of were grown using chemical transport with iodine. These components form a continuous series of solutions over the entire range of x, 0 to 1. The wurtzite structure was produced over the entire range. The lattice parameters and the composition of the solid solutions were determined to approximately 1% using x‐ray diffractometry techniques. The results provide a definitive calibration of lattice constants for the wurtzite structure of solid solutions of and and allow the analysis of samples. The variation of lattice parameters with composition was found to obey Vegard's law. The variation of the c/a ratio with composition was also linear. The ideal ratio, assuming close packing of hard spheres, occurred at 70% . The volume relationship with composition showed a slightly negative deviation from linearity. A least squares method for refining lattice parameters is described.
