An essential guide to high-purity Quartz Glass, the critical material for maximizing germicidal efficacy in UV water treatment.
In the engineering of UV-C water disinfection systems, the selection of transparent material is the most critical factor influencing performance. High-purity fused quartz glass is the undisputed industry standard, chosen for its unique ability to transmit the high-energy germicidal light (200-280nm) that inactivates waterborne pathogens. As a specialist manufacturer, FG Quartz delivers OEM-grade quartz components that form the foundation of effective and reliable water treatment systems worldwide.
The Critical Role of Material Purity
Our Quartz Glass is engineered to overcome the two primary causes of UV-C transmission loss:
1. Metallic Impurities
Trace metals like iron (Fe) or titanium (Ti) within the glass structure strongly absorb UV energy. Our commitment to using ultra-high purity raw materials (SiO₂ > 99.99%) ensures these absorbing impurities are minimized, allowing the maximum number of photons to pass through to the water for disinfection.
2. Hydroxyl (OH) Content
The presence of water, in the form of OH groups, creates strong absorption bands around 273nm. Our advanced manufacturing process creates a synthetic Quartz Glass with exceptionally low OH content (< 5 ppm), guaranteeing the highest possible transmission rate across the entire germicidal spectrum.
Engineered for Peak Performance and Longevity
Thermal Stability
With a low coefficient of thermal expansion, it withstands extreme thermal shock without fracturing.
Chemical Inertness
Resists acids and does not leach contaminants, ideal for ultrapure water applications.
UV Stability
High resistance to solarization ensures a long service life without clouding or degradation.
Mechanical Integrity
Provides a durable, pressure-rated barrier that protects expensive UV lamps from physical impacts.
Our Commitment to Quality
Raw Material Certification
Trust is built on consistency. We only source raw materials with a certified chemical analysis report, ensuring purity from the very start of the manufacturing process.
In-Process Metrology
Key dimensions, tolerances, and surface characteristics are monitored throughout the manufacturing process using advanced metrology equipment to ensure every part meets specification.
Final Optical Inspection
Each finished part is inspected for scratches, bubbles, and other imperfections, with transmission data available upon request. This dedication ensures every component meets or exceeds the standards for high-performance UV systems.
