Quartz Purity

PCT Systems Quartz Tanks Start With The Highest Grade Raw Quartz Material Specially Made For The Semiconductor and Related Industries

How Its Made

• 99.98% pure quartz sand from the Mountains of Ohio
• The highest grade quartz raw material in the world
• Additional handling and purification is done to the raw material significantly improving the overall purity
• Diamond blade and laser cutting to size
• Highly Polished
• Flame welding by the best in the industry
• Annealed to relieve thermal stress

Ultra High Purity flame fused quartz is manufactured by a continuous process in which highly refined quartz sand is fed through a high temperature flame and deposited on the surface of a melt contained in a tank lined with refractory material. The viscous melt is withdrawn slowly through a die in the bottom of this tank, and it solidifies in a shape determined by the die. When making the sheet material for our Tanks the ingot of transparent fused quartz with a rectangular cross-section is cut off at intervals, and removed for further processing.
