The refractive index determines how much the path of light is bent, or refracted, when entering a material.This is described by Snell''s law of refraction, n 1 sinθ 1 = n 2 sinθ 2, where θ 1 and θ 2 are the angles of incidence and refraction, respectively, of a ray crossing the interface between two media with refractive indices n 1 and n 2.

Buying Scrap Carbide - National Scrap Carbide Buyers
19/8/2020· If you don’t know if you have carbide that is no problem…just make sure you keep it separate and we will use our metal analyzer to confirm that it is carbide. Carbide end mills and carbide bits are some of, if not the most common tungsten based items that we get in for scrap, so if you think that you have some other type of carbide or tungsten material bring it in to us.

PECVD silicon carbide deposited at different temperature
PECVD silicon carbide films were deposited in a high frequency parallel-plate plasma reactor. The deposition temperatures were 250, 350 and 450 °C respectively. The concentration of species in the SiC films was determined by Rutherford backstering spectrometry (RBS). Chemical compositions were analyzed by infrared spectroscopy (IR). The IR spectra were measured from 4000 to 400 cm−1. The
