Growth of Ruby Crystals from Solution

摘要

LiF-AlF3 solvents were used to grow large ruby crystals by a process based on the thermal-gradient technique. In developing the method and endeavoring to obtain the necessary control over the process, important factors such as temperature, temperature gradients, solvent composition, solute concentration, degree of agitation of the solution, seed-crystal rotation rate, and system geometry were studied as variables.
