The two most common ores of zirconium are zircon, or zirconium silicate (ZrSiO 4 ); and baddeleyite, or zirconia or zirconium oxide (ZrO 2 ). The amount of zirconium produced in the United States is not reported. That information is regarded as a trade secret. The largest suppliers of zirconium minerals in the world are Australia and South Africa.
Zircons are tiny crystals of zirconium silicate (ZrSiO4) that originate in igneous rock, which forms when volcanic magma cools. It's a very stable mineral that melts at 2550°C. Zircon is harder than quartz and almost as hard as diamond. Because of these characteristics, zircon is the mineral most frequently used in various radioisotope dating methods for dating …
Ultrafine zirconium silicate, being a naturally occurring mineral, offers an environmentally friendly alternative to synthetic additives and fillers, appealing to environmentally conscious ...
Zircon crystals—zirconium silicate to be precise—have become a very important age dating medium for geologists. Let's take a look at why, how geochronology analysis is done, and what types of applications are being made of this technology. This article, the third in a series of three articles focused on geochemistry for fall and winter of ...

What exactly is zirconia? Much of the confusion surrounding this material has to do with its name. The word "zirconia" has many associations, including a mineral (zircon, or zirconium silicate, ZrSiO4), an atomic element (the metal zirconium, Zr), and even a synthetic gemstone (cubic zirconia) – making it very easy to misunderstand what makes …
Zircon, a zirconium silicate, is currently the most important commercial zirconium-bearing mineral. Baddeleyite, a natural form of zirconia, is less important but has some specific end uses. Both zircon and baddeleyite occur in hard-rock and placer deposits, but at present all zircon production is from placer deposits. Most baddeleyite production is from hard-rock …
