An Apparatus for the Production of Large Metallic Crystals by Solidification at High Temperatures,

Abstract

The commercial production of large single crystals is rapidly making available specimens of inorganic compounds for research purposes and special applications. The Harshaw Chemical Company is growing halide crystals in pound denomination; the earlier researches of Stockbarger are being used to good advantage. The Verneuil Method for preparing synthetic sapphires has been developed by the Linde Air Products who are producing not only large sapphires, but a number of other refractory oxides. Considerable interest in the problem of growing adequate sized piezoelectric quartz crystals has been manifested, and progress is being made in this direction.
