Sales of transparent ceramic materials worldwide will grow at a compound annual growth rate (CAGR) of 19.0% in the next five years, reaching $765.9 million by 2024.

Transparent ceramics are defined as inorganic, nonmetallic polycrystalline materials that transmit light with wavelengths in the visible electromagnetic spectrum. A ceramic is considered transparent when its real in-line transmission is 60% or higher at wavelengths between 300 nm and 800 nm in samples that have a minimum thickness of 0.8 mm. In recent years, the definition has expanded to include materials that also allow light with wavelengths in the ultraviolet and infrared regions of the spectrum to pass through.
