UV vs. IR Grade Fused Silica

UV grade fused silica is manufactured synthetically through the oxidation of high purity silicon by flame hydrolysis. 2 The UV grade demonstrates high transmittance in the UV spectrum, but there are dips in transmission centered at 1.4m, 2.2m, and 2.7m due to absorption from hydroxide (OH-) ion impurities.

Corning closes refractories plant due to declining demand

Jun 17, 2014Corning Inc. purchased the plant in the early 1900s to manufacture clay pots used in glass making. That process evolved into producing temperature-resistant products used in glass-melting furnaces and other applications. The plant was expanded in 1998 to make products for Corning Inc.'s high-purity fused silica business.

From Glass to Fused Silica in Corning, NY, USA

I couldn't ignore the connection to chromatography when the exhibit started explaining how Corning chemist J. Franklin Hyde made fused silica in 1934 from pure liquid chemicals instead of melting dry mineral ingredients like other glass products. Fused silica therefore, has a much higher melting temperature than other traditional glasses.
