The unique properties of the fused quartz make quartz crucibles and lids better than their counterparts made of other materials.
Based in Waterford, New York, Momentive develops and manufactures specialty silicones and silanes, as well as fused quartz and specialty ceramics products.
Over time, other families of transparent soils have been developed for geotechnical testing, including silica gel [6], hydrogel [7], fused quartz [8], and laponite [9].
Since 1992 Rayotek has engineered and manufactured sapphire, glass, fused quartz and fused silica products, enabling world class companies to bring cutting-edge products to market.
In addition to the carbon-fiber truss tube, a trio of cooling fans for the primary mirror, a dual-speed 3-inch Crayford-style focuser, and a pair of Losmandy-style dovetail mounting bars, the scope features both mirrors made of fused quartz. With the exception of Questar telescopes, this thermally stable material has rarely been offered as an option for amateur scopes (and even in the case of the already pricy Questar, a quartz mirror added a roughly 25% premium to the cost).
Made from highly polished fused quartz, the plates are suitable for the most demanding cell-based assay requiring monitoring in the UV region down to 200 nm.
Other in-stock substrates include BK-7; Corning 0211; Corning Eagle 2000 XG; Corning ULE; Glaverbel float; OCLI front surface mirror; Pilkington Optiwhite; PPG Starphire; Schott's AF-37, AF-45, and B-270; fused silica; fused quartz, and more.
Here we present the experimental study of MG deposited on a fused quartz substrate in the frequency range of 325-500 GHz by using both pulsed and CW techniques at room temperature.
Coined as the 'Superman' memory crystal, as the glass memory has been compared to the "memory crystals" used in the Superman films, the data is recorded via self-assembled nanostructures created in fused quartz, which is able to store vast quantities of data for over a million years.
The mineral oil has the same index-of-refraction as fused quartz near laboratory room temperature, is odorless, non-toxic, relatively nonflammable and non-volatile, inexpensive, and very stable.
