Selenium

硒是具有符号Se和原子序数为34的化学元素。它是一种非金属,具有介于其周期表列相邻硫属元素硫和碲之间的性质。 它本质上很少发生在其元素状态,或作为纯矿化合物。 硒在1817年被JönsJacob Berzelius发现,他注意到新元素与以前已知的碲的相似性。 硒在金属硫化物矿中不纯化,其中部分替代了硫。 在商业上,硒是在这些矿石的精炼中作为副产物生产的,最常见的是在铜生产过程中。 纯硒化物或硒酸盐化合物的矿物是已知的,但是是罕见的。 今天硒的主要商业用途是玻璃制造和颜料。 硒是半导体,用于光电池。 一般重要的电子产品的使用主要取决于硅半导体器件。 硒继续用于几种类型的直流电源浪涌保护器,婴儿配方和一种荧光量子点。 Selenium is a chemical element with symbol Se and atomic number 34. It is a nonmetal with properties that are intermediate between those of its periodic table column-adjacent chalcogen elements sulfur and tellurium. It rarely occurs in its elemental state in nature, or as pure ore compounds. Selenium was discovered in 1817 by Jöns Jacob Berzelius, who noted the similarity of the new element to the previously known tellurium. Selenium is found impurely in metal sulfide ores, where it partially replaces the sulfur. Commercially, selenium is produced as a byproduct in the refining of these ores, most often during copper production. Minerals that are pure selenide or selenate compounds are known, but are rare. The chief commercial uses for selenium today are in glassmaking and in pigments. Selenium is a semiconductor and is used in photocells. Uses in electronics, once important, have been mostly supplanted by silicon semiconductor devices. Selenium continues to be used in a few types of DC power surge protectors, baby formula, and one type of fluorescent quantum dot.

在英语 词典里selenium的定义

字典中硒的定义是以几种同素异形体存在的非金属元素。 它在火山区和硫化物矿石,特别是黄铁矿中是游离的。 常见的形式是灰色结晶固体,它是光电导,光伏和半导体:用于光电池,太阳能电池和静电复印。 符号:Se; 原子序号:34; 原子量:78.96; 化合价:-2,4或6; 相对密度:4.79; 熔点:221℃; 沸点:685℃。

The definition of selenium in the dictionary is a nonmetallic element that exists in several allotropic forms. It occurs free in volcanic areas and in sulphide ores, esp pyrite. The common form is a grey crystalline solid that is photoconductive, photovoltaic, and semiconducting: used in photocells, solar cells, and in xerography. Symbol: Se; atomic no: 34; atomic wt: 78.96; valency: –2, 4, or 6; relative density: 4.79 ; melting pt: 221°C ; boiling pt: 685°C.
