The refractive index of boron carbide?

The refractive index of boron carbide?
Boron carbide is a non -metallic ceramic material composed of carbon and boron elements. The chemical formula is BCX. It has high hardness, high melting point, low density and excellent thermal performance, so it is widely used in many fields. Boron carbide has a high refractive index, making it particularly important in the field of optics
Boron carbide is a ceramic material with high refractive index. Through Sieier’s Law, Ellipular Folding Method, and Gallery refraction spectrum method, the refractive index of boron carbide can be measured. The refractive index of boron carbide is affected by the wavelength and temperature and has certain application characteristics. The high refractive index of carbonization makes it have a wide range of prospects in the field of optics.
