Standard Characterization Methods for the Determination of the Quality of Hydrothermally Grown Quartz,

Abstract

Standard characterization techniques have been developed for the determination of the Q and the etch channel density of hydrothermally grown single crystal alpha quartz. Y-cut slices, for infrared Q evaluation, and AT-cut slices, for etch channel determinations, were respectively lapped to a three micron finish at a final thickness of 6.35mm + or - 0.03mm. In order to properly characterize the Q of the as-grown quartz, the sample should be linearly translated through the beam so that a complete profile along the Z axis is obtained. To eliminate differences due to averaging techniques, the maximum alpha value calculated from the scan should be employed to safely characterize the Q of the quartz. Utilizing standard samples, the repeatibility of any alpha value was found to be less than or equal to + or - 0.004.
