baddeleyite

baddeleyite

1. A lustrous gray strong metallic element resembling titanium,it is used in nuclear reactors as a neutron absorber; it occurs in baddeleyite but is obtained chiefly from zircon.

一种有光泽、灰白色、坚固的金属元素，类似钛，在核反应堆中用作中子吸收剂，见于斜锆石中。

2. "The metal is hard and Brittle when impure, soft and ductile when highly purified. It is relatively abundant, occurring as zircon (also marketed as a natural gemstone) and Baddeleyite."

不纯的锆是硬而脆。高纯度的锆为质软、具有延展性的金属,锆的丰度相当高,以锆石矿和斜锆石矿的形式存在。

3. Also baddeleyite is used in lab crucibles.Used in high-performance pumps and valves.Clear zircon (ZrSiO4) is a popular gemstone.

元素用途:Used in alloys such as zircaloy which is used in nuclear applications since it does not readily absorb neutrons.

7. Porous ceramic materials on the base of strontium zirconate were developed with zirconium dioxide,baddeleyite powder,and granular polysterol.

采用二氧化锆、斜锆矿粉、碳酸锶及粒状聚苯乙烯制成了锆酸锶多孔陶瓷材料。
