2008/2/27· All flat surfaces are polished at first with fins silicon 400 - 600 grit silicon carbide particles on a steel plate. The pieces are washed and final polishing was done with cerium oxide powder. In your case to remove oxidation only, start of with cerium oxide, water and a soft slow moving felt wheel.
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.

2020/8/8· Refractive index, also called index of refraction, measure of the bending of a ray of light when passing from one medium into another. If i is the angle of incidence of a ray in vacuum (angle between the incoming ray and the perpendicular to the surface of a medium, called the normal) and r is the angle of refraction (angle between the ray in the medium and the normal), the refractive index n
2018/1/18· 1. A powdery filler for dental filler materials comprising particles of feldspar or feldspar derivatives having a mean particle diameter (d50) of from 0.5 to 5 μm, said particles having a coating with a silicon compound containing reactive groups said dental filler 2.
Data are used in coination with particle size distributions to estimate the complex refractive index of each dust sample. Our results show that the magnitude and spectral dependence of the dust extinction and refractive indices differ according to particle mineralogy, suggesting the necessity for regionally resolved optical properties for modeling dust radiative effects in the longwave.

With silicon-based LEDs overcoming issues such as lattice-mismatch and refractive-index problems, JOHN ELLIS, chief engineer at Plessey Semiconductors, predicts that the LED industry will move to take advantage of the lower-cost substrate used in the broad IC industry.
Silica is one of the most abundant oxides in the earths crust. It exists in 3 crystalline forms as well as amorphous forms. It hasmany useful properties and is used in a range of appliions such as silicon, elctronics, refractories, sand, glass making, building
Moissanite is known for its refractive index of 2.65, which is notably higher than a diamond at 2.42 or sapphire at 1.76. The higher the refractive index, the higher the brilliance, which looks like bright light traveling out of the stone. One of the most visibly
2012/8/12· If the particles are assumed to have the same radii and be spherical then the maximum change in Bond albedo (ΔA) occurs at a particle size of about 0.1 μm and refractive index of about 3.4.
Moissanite''s very high refractive index ("fire") also allows Moissanite to better retain it''s fire if it gets dirty, oily, or smudged, (unlike CZs that look very dull when dirty). These color/clarity characteristics are another reason that Moissanite looks like a diamond & not like a Cubic Zirconia (CZ).
