PREPARATION OF DEUTERATED COLEMANITE
Abstract
The preparation of deuterated colemanite was undertaken to provide sufficient material to allow a comparison of its ferroelectric properties with that of naturally occurring mineral colemanite and also with synthetic normal colemanite. The reactants, deuterated Borax (Na2B4O7.10D2O) and Meyerhofferite (2CaO.3B407. 7D2O) were prepared. Two reactions were performed to produce the colemanite. In the first reaction the Meyerhofferite and Borax were reacted with D2O and normal colemanite seeds at 68 Cfor 56 days. Conversion to deuterated colemanite was complete. The second reaction was modified slightly by using fewer grams of the reactants in the same ratio as in the first reaction. After 88 days at 68C only about 50% conversion occurred.
