Situated in the heart of the Appalachian Mountains, Spruce Pine is home to the world’s highest quality quartz and has been mined for more than a century.
is used in a range of high-tech applications, including:
- Semiconductor: for the manufacture of fused quartz crucibles used in the Czochralski (CZ) process, and the production of fused quartz tubing and ingots used to create fabricated quartzware for the semiconductor wafer process.
- Photovoltaic Cells: for the manufacture of crucibles for CZ single crystal silicon growth.
- Quartz Lighting: including automotive xenon, halogen, HID and UHP lamps.
