Silicon dioxide, also known as silica, is an oxide of silicon with the chemical formula Si O 2, most commonly found in nature as quartz and in various living organisms. In many parts of the world, silica is the major constituent of sand. SiO 2 Molar mass 60.08 g/mol
Silicon carbide powder is used as an abrasive for such as grinding wheels, whetstone, grinding wheel, sand tiles etc.. Silicon carbide is used to produce epitaxial graphene by graphitization at high temperatures. It is also acts asthe metallurgical deoxidizer material.
“It’s transparency and high refractive index makes it a challenging material to inspect for surface defects that may potentially impact epitaxy growth or final device yield.” During the manufacturing flow, SiC substrates are prone to various defect types, such as crystalline stacking faults, micropipes, pits, scratches, stains and surface particles.
Clouds of solid particles are present in many regions of the Solar System (comets, interplanetary dust cloud, planetary atmospheres). These clouds can be remotely studied by the light they ster. There is a need for a data base of the light stered by a large variety of samples at different wavelengths to interpret such measurements. The PROGRA2 instruments are used for this purpose. The
Now HTML access to files with the optical constants of astronomical silie, graphite, PAH-graphite, and silicon carbide very often used in astrophysics. Optical constants of water (and ice) A collection of data for water and old Warren''s code compiling the refractive index of water ice (a updated code is here ).

2 Guptaetal. optical properties (refractive index, dielectric constant) of a small composite particle, comprising a mixture of two or more materials, are approximated by a single averaged opti-cal constant and then Mie theory or T-Matrix is used to cal-culate absorption
Also, the array of concave depressions was directly used as a mould for repliion of KER-2500 transparent polymeric silicon from Shin-Etsu with a refractive index n=1.41. The perfectly matched array of micro-lenses can be detached from substrate and used as a local solar concentrator.
He discovered microscopic particles of the gem that would eventually bear his name in Arizona, in a crater created by a meteorite that fell to Earth. He initially thought that he discovered diamonds, but later determined that the crystals were actually composed of silicon carbide (whereas diamonds are …
We suspect this difference may be due to the very high refractive index of those particles, although differences in particle microstructure may also be important. Two samples produced positive linear polarization which had a single broad maximum near 100° stering angle, and a magnitude greater than 40% at some wavelengths.
