名称由来:From the mineral, zircon.
元素描述:Gray-white, lustrous, corrosion-resistant metal.
元素来源:Found in many minerals such as zircon and baddeleyite.
元素用途:Used in alloys such as zircaloy which is used in nuclear applications since it does not readily absorb neutrons. Also baddeleyite is used in lab crucibles. Used in high-performance pumps and valves. Clear zircon (ZrSiO4) is a popular gemstone.
