"日業者證實 中國21日起禁止對日出口稀土
〔編譯陳成良/綜合報導〕儘管中國否認向日本禁運稀土,但日本多家貿易公司二十四日表示,中方已停止對日出口稀土。紐約時報訪問到中國、日本及北美八名稀土產業的主管、分析師及貿易商,他們一致表示,中國二十一日起即對日實施稀土出口禁令。
東京貿易商雙日(Sojitz)公司發言人告訴法新社:「我們收到中方官員知會,中國已從九月二十一日起停止出口稀土到日本。」另家不願具名的貿易商也透露,中國商務部二十二日在北京召見擁有稀土輸日執照的中國公司開會,討論停止稀土輸日的事宜。
日本內閣官房長官仙谷由人二十四日表示,目前尚未接獲中國政府的正式通知,但他承認,有接獲貿易公司消息,指中國稀土對日出口的通關手續出現遲滯,日方正在查證,之後將採取適當措施。
中國商務部二十三日矢口否認有紐約時報所報導的禁止稀土輸日之事。業界人士看法是,暫停對日本出口稀土,是由中國海關官員下手,而不是透過中國商務部正式發布禁運令,以增加北京對日本的談判空間。"
稀土金屬,或稱稀土,是元素周期表中鈧、釔和鑭系元素等化學元素的共同的俗稱。稀土是很多科技產品的材料。
As defined by IUPAC, rare earth elements or rare earth metals are a collection of seventeen chemical elements in the periodic table, namely scandium, yttrium, and the fifteen lanthanides.[1] Scandium and yttrium are considered rare earths since they tend to occur in the same ore deposits as the lanthanides and exhibit similar chemical properties.
The term "rare earth" arises from the rare earth minerals from which they were first isolated, which were uncommon oxide-type minerals (earths) found in Gadolinite extracted from one mine in the village of Ytterby, Sweden. However, with the exception of the highly-unstable promethium, rare earth elements are found in relatively high concentrations in the earth's crust, with cerium being the 25th most abundant element in the Earth's crust at 68 parts per million.
