Abstract

This work is a continuation of the work on the preparation of high purity, low dislocation quartz being performed at RADC. Several methods have been investigated for the preparation of high purity materials. The effect of seed pretreatment is also discussed.

Abstract

Using low growth rates and high purity nutrient, high purity quartz can be produced without the use of a linear. The most promising synthetic seed material found thus far is from the X growth area of the crystal. The Q of the X seed crystals appears to be over 2 million., This article is from the Proceedings of the Symposium on Frequency Control (36th Annual), 2-4 Jun 82, Philadelphia, PA., AD-A130 811, p55-61.
