Desiccant:

A final category of oxide, monocrystalline substances is that the chalcogenides, that area unit fashioned by melting along the grouping parts sulfur, selenium, or chemical element with parts from cluster V (e.g., arsenic, antimony) and cluster IV (e.g., germanium) of the table. attributable to their conductive properties, chalcogenides have found use in threshold and memory switch devices and in photography. A connected end-member of this cluster is that the elemental amorphous semiconductor solids, like amorphous Si (a-Si) and amorphous semiconductor (a-Ge). After silicon oxide desiccant , the numerous “soda-lime” glasses have as their primary constituents soda, or metallic element chemical compound (Na2O; typically derived from washing soda, or soda ash), and lime, or quicklime (CaO; usually derived from roast limestone). to the present basic formula alternative ingredients is also additional so as to get varied properties. as an example, by adding halide|salt} or metal fluoride, a...

Silica Gel:

  Another silicagel variation is salt glass that is employed wherever high thermal shock resistance and high chemical sturdiness area unit desired— as in chemical tableware and automobile headlamps. within the past, leaded “crystal” ware was fabricated from glass containing high amounts of lead chemical compound (PbO), that imparted to the merchandise a high ratio (hence the brilliance), a high modulus of elasticity (hence the plangency, or “ring”), and a protracted operating vary of temperatures. Lead chemical compound is additionally a significant part in glass solders or in waterproofing glasses with low firing temperatures.   silica gel in thermal properties in addition as cost; glass fibers like E glass and S glass, employed in fiber-reinforced plastics and in thermal-insulation wool; and optical glasses containing a mess of further major constituents. chemical compound glasses not supported silicon oxide area unit of very little industrial importance. they're usually...
