Hydroxyl Content
Ultra-low hydroxyl quartz, crafted through precise fusion, offers minimal OH content for top-tier optical clarity and stability, ideal for accurate “beta factor” measurements.
Reactivity
Fused quartz’s exceptional low reactivity makes it ideal for high-purity applications, where it resists contamination and chemical interactions, ensuring the integrity of sensitive processes and materials.
Permeability
Fused quartz offers unparalleled control over permeability, making it ideal for precision applications requiring exceptional stability and performance.
Mechanical Properties
Fused quartz is strong in compression (1.1 x 10⁹ Pa) and tension (4.8 x 10⁷ Pa), but surface flaws reduce strength, so 0.68 x 10⁷ Pa is the recommended design stress.
Electrical Properties
Fused quartz excels in insulation and low-loss dielectrics, maintaining performance at high temperatures and broad frequencies.
Optical Properties
Fused quartz provides outstanding optical clarity and stability across a wide wavelength range, making it perfect for precision optical and photonic applications.
Thermal Properties
One of the most important properties of fused quartz is its extremely low coefficient of thermal expansion: 5.5 x 10–7 /°C (20–320°C). Its coefficient is 1/34 that of copper and only 1/7 of borosilicate glass.
Rupture Calculations
Fused quartz rupture calculations are essential for understanding its tensile limits and ensuring reliability in high-stress applications, where precision and material integrity are critical.
Usage Guidelines
Momentive Technologies backs its products with fully equipped analytical and development laboratories and a staff of materials and fusion experts available to support customer requirements.
