Description: GE 124 is a very pure fused quartz, made from crystalline silica.GE 124 is very similar to fused silica, with the exception of less transmission in the UV spectrum and much lower OH content.Other features besides its purity include excellent thermal properties and high Materials: UV Grade Fused Silica
3M fused silica products are optimized for purity and consistency. Our revolutionary furnace design helps prevent raw silica sand from becoming contaminated during processing, resulting in a product that is 99.7% pure. 3M fused silica products are optimized for batch-to-batch consistency for a more accurate mold and faster overall production.
For fused silica, a numerical calculation was required to compute frequency corrections for the combined ramp/shock waveforms produced in the experiments. In both cases the behavior of the refractive index over the density range of the data was found to be predicted quite accurately by adding a correction term to the Gladstone-Dale relation.

Chemical vapor deposition is the process used to manufacture fused silica. This high-temperature process creates glass by depositing layer after layer of tiny glass particles on a growing surface. Corning supplied fused silica for ultrasonic delay lines used by the United States military to detect Soviet missiles.
Fumed silica (CAS number 11), also known as pyrogenic silica because it is produced in a flame, consists of microscopic droplets of amorphous silica fused into branched, chainlike, three-dimensional secondary particles which then agglomerate into tertiary particles. The resulting powder has an extremely low bulk density and high surface area. Its three-dimensional …
Capillary micro components are fused silica or quartz tubing, which has been reshaped to modify the end face geometry and/or the axial diameter. Ferrules and sleeves used in optical fiber applications are typically 2.00mm or less in outer diameter; the choice of material is often based on the application wavelength.
