Zircon, scientifically known as zirconium silicate (ZrSiO4), is a naturally occurring mineral found in the Earth's crust. It is a dense, hard, and durable mineral that typically appears as small, reddish-brown to grayish crystals. Zircon contains the elements zirconium and silicon, along with trace amounts of other elements such as hafnium, …
The price range for 65pc-grade zirconium silicate was assessed this week at 15,000-15,500 yuan/t ($2,318-2,395/t) on an ex-works China basis, up from Yn14,500-15,000/t in the previous assessment on 15 June and its highest level since December 2012. Prices have climbed in five of the past seven weeks.

The zirconium atom has a radius of 160 pm and a Van der Waals radius of 186 pm. Zirconium was discovered by Martin Heinrich Klaproth in 1789 and first isolated by Jöns Jakob Berzelius in 1824. In its elemental form, zirconium has a silvery white appearance that is similar to titanium. Zirconium's principal mineral is zircon (zirconium silicate).
During the heating process, the zirconium silicate crystal structure re-arranges into amorphous silica and zirconium oxide phases. On fast cooling, …
