OPTIMIZING BOROLANTHANIDE-GLASS POLISHING PROCESSES

The processing parameters for polishing borolanthanide glasses with fo rmulations based on zirconium dioxide and basic zirconium sulfate are optimized. The factorial dependence of the process on the temperature of the medium, the polishing pressure and rotation rate, and the compo sition of the polishing suspension is studied. It is established that the optimum concentration of basic zirconium sulfate in a zirconium-co ntaining suspension is determined by the total concentration of boron, barium, and lanthanum oxides in the glass being processed.
