Suitability of quartz sands for different industrial applications

摘要

Quartz is found in the nature in varying purity and is traded in varying quality for different industrial applications. It can be used either for high added value applications such as silicon-metal wafers , optical glass or PV panels or for more ordinary applications such as foundry sand for metal castings or as a filler for adhesives and grouts. Extended exploration work in area of central Macedonia , resulted in the identification of medium purity quartz river deposits. Preliminary laboratory tests verified the suitability of these quartz sands to be used as filler materials for making adhesives and grouts.
