Characteristics
Appearance: yellow, in the air in the light will quickly turn into red.
Density: Relative density is about 5.27g/cm³.
Hardness: relatively soft hardness, Knoop’s hardness is 110 – 130kg/mm.
Melting point: Relatively high melting point, about 1525°C.
Transmission range: It has good optical properties, with a transmission range of 0.5 – 15μm, high transmittance of infrared light with a wavelength of less than 15μm, and low scattering in the whole transmission band, which makes it widely used in the optical field, such as making infrared optical instruments.
Refractive index: The refractive index is high, for example, at 10.6μm wavelength, the refractive index is about 2.4028.
Stability, zinc selenide is relatively stable at room temperature, but it is easy to decompose when left in the air for a long time or when it meets dilute nitric acid, and it is insoluble in water.
It will oxidize to selenium dioxide and zinc oxide when heated to a certain temperature in air.
Reactivity: H₂Se will be generated when reacting with dilute acid, which is toxic and requires attention to safety protection during storage, transportation and use.
