Zircon ( / ˈzɜːrkɒn, - kən /) [ 7][ 8][ 9] is a mineral belonging to the group of nesosilicates and is a source of the metal zirconium. Its chemical name is zirconium (IV) silicate, and its corresponding chemical formula is Zr SiO 4. An empirical formula showing some of the range of substitution in zircon is (Zr 1–y, REE y ) (SiO 4) 1 ...
Hadean zircon is the oldest-surviving crustal material from the Earth's earliest geological time period, the Hadean eon, about 4 billion years ago. Zircon is a mineral that is commonly used for radiometric dating because it is highly resistant to chemical changes and appears in the form of small crystals or grains in most igneous and metamorphic host rocks.
Zircon. Andrew Aversa (born June 23, 1987), [ 1] known professionally as zircon, is an American electronic musician, composer, and audio technician primarily known for his work on video game soundtracks, including Super Street Fighter II Turbo HD Remix, Monkey Island 2: LeChuck's Revenge Special Edition, Soulcalibur V, Pump It Up, and ...
Zirconium dioxide ( ZrO. 2 ), sometimes known as zirconia (not to be confused with zircon ), is a white crystalline oxide of zirconium. Its most naturally occurring form, with a monoclinic crystalline structure, is the mineral baddeleyite. A dopant [clarification needed] stabilized cubic structured zirconia, cubic zirconia, is synthesized in ...

ZTR index. The ZTR index is a method of determining how weathered, [1] both chemically and mechanically, a sediment (or a corresponding sedimentary rock) is. The letters in ZTR stand for 3 common minerals found in ultra-weathered sediments: zircon, tourmaline, and rutile. Other minerals that can be used alongside the ZTR index are garnet ...
Yttria blends of approximately 3% are called either tetragonal polycrystalline zirconia or tetragonal zirconia polycrystal (forming the initialisms TZP or TPZ) and have the finest grain size. These grades exhibit the highest toughness at room temperature, because they are nearly 100% tetragonal, but this degrades severely between 200 and 500 ...
