Abstract

The results of an IR spectroscopic study of the content of water and hydrogen defects in hydrothermal and pegmatite quartz from quartz-vein occurrences in Karelia (North-West Russia), considered as a promising source of high-purity quartz raw materials, are presented. It is shown that the main amount of water in the analyzed quartz is in molecular form, and OH groups associated with aluminum, lithium, and boron trace elements in the quartz lattice are also identified. Granular quartz with the lowest content of molecular water and OH-groups is the most preferred for use as a high-purity quartz raw material.
