当你打开彩色电视机,观赏五颜六色的各种电视节目时,你可曾想到一种稀有金属——锶吗? 纯锶呈银白色,质轻具延展性,其化学性质活泼,极不稳定,易与氧、氢等反应,生成氧化物、氢化物及氢氧化物。自然界中含锶矿物有三十多种,但具工业意义的锶矿物只有天青石和菱锶矿。锶是制造彩色电视机显像管荧光屏玻璃的重要材料,这一用途占锶工业生产比例的62%;另外制造曳光弹、信号弹、火箭信号装置,以及节日之夜灿烂瑰丽的礼花、焰火等,占锶工业生产比例15%;锶磁性体占7%;颜料和填充料制造占4%;锌电解提纯占3%;其它用途占9%。
When you turn on the color TV, watch a variety of television shows, you have thought of a rare metal - strontium? Pure strontium silver, light ductile, chemically active, very unstable, Easy with oxygen, hydrogen and other reactions, generating oxides, hydrides and hydroxides. There are more than thirty kinds of strontium minerals in nature, but only industrially strontium minerals are celestite and strontianite. Strontium is an important material in the manufacture of color television picture tube screen glass for this purpose accounting for 62% of the total industrial production of strontium. In addition, strokes, firearms, rocket signals and brilliant fireworks, Production ratio of 15%; strontium magnetic accounted for 7%; pigment and filler manufacturing accounted for 4%; zinc electrolysis purification accounted for 3%; other uses accounted for 9%.
