The principal commercial source of zirconium is the silicate mineral, zircon (ZrSiO 4), which is found primarily in Australia, Brazil, India, Russia, South Africa and the United States, as well as in smaller deposits around the world.aturally occurring zirconium is composed of five isotopes. 90 Zr, 91 Zr, 92 Zr and 94 Zr are stable. 94 Zr can undergo double beta decay (not observed experimentally) with a half-life of more than 1.10Ã10 17 years. 96 Zr has a half-life of 2.4Ã10 19 years, making it the longest-lived radioisotope of zirconium.
