Abstract
THE extensive use of quartz in piezoelectric oscillators has stimulated the production of synthetic quartz crystals. Spezia1 in 1906 grew quartz at a temperature somewhat below 300° C. from an aqueous solution containing sodium metasilicate and sodium chloride. His method was to dissolve quartz in the hotter part of the container and deposit it in the cooler part. We have repeated Spezia's experiments so far as to confirm his results, but the period of months which is required for appreciable growth to occur makes the method unsuitable for industrial production.
