Melting Point: 790C Chemical properties Nickel subsulfide is not soluble in water, or in organic solvents. The refractive index of X-rays is slightly less than 1.0, which means that an X-ray entering a piece of glass from air will be bent away from the normal, unlike a ray of light, which will be bent toward the normal. Refractometry is a qualitative and non-destructive technique that is based on Snell's law. Refractive indices, relative to a vacuum, are 1.000292 for air, 1.333 for water, 1.156 for crown glass, and 1.475 for silica glass (SiO 2). It is a cofactor of the enzyme UREASE.
