New chlorination process step for production of ultra high purity quartz sand.

Offentlig prosjektsammendrag

The Quartz Corp (TQC) is a major supplier of High Purity Quartz sourced from its sites in Spruce Pine (USA) and Drag (Norway). As part of a significant investment plan, TQC will build a thermal gas treatment plant in order to implement a new process step in Drag, Tysfjord which will enable it to manufacture ultra high purity quartz. Thermal gas treatment will be applied to significantly reduce impurities such as alkali metal, alkaline-earth metal, and transition metal that can lead to defects in the quartz glass products, while improving the mechanical stability of quartz glass used at high temperatures. The knowledge and skills gained during the project will be used to improve the manufacturing process and produce a superior quartz product for the most demanding high tech markets including semiconductor, fiber optics and long-life PV crucibles.
