碧玺简介

作者:敏敏 点击:次 时间:2009-11-06 10:09

      碧玺又称为电气石,英文名称Tourmaline,是从古僧伽罗(锡兰)语Turmali一词衍生而来的,意思为“混合宝石”。传说碧玺的来历是在西元1703年,荷兰的阿姆斯特丹有几个小孩玩著荷兰航海者带回的石头,并且发现这些石头除了在阳光底下出现的奇异色彩外,更惊讶这些石头有一种能吸引或排斥轻物体如灰尘或草屑的力量,因此,荷兰人把他叫做吸灰石。一直到西元1768年,瑞典著名科学家林内斯发现了碧玺还具有压电性和热电性,这就是电气石名称的由来。一直到现在,碧玺还常在科学上被用于发光强度与压力变化的测定,在二次大战当初,是唯一可以判定核爆压力的物质,现在,则被广泛运用于光学产业。
