Ruby crystals were grown from molten salt solutions consisting of mixtures of PbO and PbF2. Using a similar method, Ga doped ruby crystals were grown. Analytical procedures for the detection of Ga in the presence of ruby were developed. Several important factors in the growth of both doped and undoped ruby crystals were found to be sensitive to the PbF2 content. Some of these factors are Al2O3 solubility, crystal habit, crystal quality, and dopant concentration. A mechanism for the growth of ruby from PbO-PbF2 fluxes is proposed. Equipment for the handling of large melts was designed. Apparatus for line width measurements was completed.
