  • properties of fused silica heraeus

    The purities of fused quartz and fused silica are outstandingly high. Synthetic fused silica from Heraeus contains total metallic contamination below 1ppm. For fused quartz the amount is approximately 20 ppm and consists primarily of Al2O3 with much smaller amounts of alkalis, Fe 2 O 3, TiO 2, MgO and ZrO 2. OH content In addition to metallic impurities, fused quartz and fused silica also contain water present as …
