Zircon is used as a glass component in television and computer monitor faceplates due to its radiation absorbing characteristics.

Cathode ray tubes (CRT’s) generate x-rays which must be attenuated to reduce the risk of radiation related health effects, principally cancer. Zircon in CRT glass acts an effective x-ray absorber and has the added benefits of increasing the strength and hardness of the glass.   Zircon is used in plasma screens to enable the manufacture of faceplate glass which is much thinner and of greater dimension.   However, the use in the TV glass sector has reduced due to increasing preference for new display methods such as liquid crystal displays/thin film transistors as against CRT.
