Research in Zircon Polarizers.
Abstract
Attempts to grow single crystals of zircon (ZrSiO4) by molten salt and hydrothermal techniques are described. Well developed crystals with (110) and (111) faces were grown up to 4 mm in size from a lithium tungstate melt. The crystal were colored pale to dark brown due to absorption of iron impurities along preferred crystallographic planes. A technique was developed for sintering high purity ZrO2 and SiO2 to yield pellets suitable for use as hydrothermal nutrient. High quality hydrothermal zircon growth was achieved on 1 x 1/2 inch (110) faces of natural zircon seed crystals. Experiments were performed in a one-inch platinum system at 500C and 29,000 psi using 3M KF as mineralizer. (Author)
