Production Engineering for Growth of Synthetic Calcite Polarizer Material
Abstract
A preliminary production engineering program was completed for the growth of synthetic calcite for crystal polarizers. Starting meterials were powdered high purity CaCO3, natural calcite of uniform composition, or solution recrystallized CaCO3. Both 1.5 and 3.0 inch diameter autoclaves were used to establish most growth variables. Solutions of 6 m K2CO3 were used for mineralizers. Techniques were perfected for the operation of silver lined autoclaves with 9.0 inch diameter x 9 feet long cavities. For runs extending up to 60 days, about 3 - 4 mm thick sections of new material were grown on seeds. A number of chemical and physical tests established the high quality reproduction of natural calcite which is used in conjunction with electrooptically Q switched lasers.
