    Zircon Zircomet LimitedZirconium Based Materials

    China has a small output of zircon sand relative to its consumption. The annual output is around 20 000 mts. The use of Chinese zircon sand has been limitd by the higher radioactivity levels which makes it unsuitable for many applications. The global supply and demand of zircon sand was thought to be fairly balanced in 2008 at m tonnes.
