摘要
锌的冶炼存在一定困难,因此它出现较晚,是古代七种有色金属中最后的一个。西方考古学家曾发掘出公元前留下的一些金属锌碎片,但这肯定是冶炼其它金属时偶然得到的,当时并未掌握锌的冶炼方法。我国和印度是生产锌最早的国家。从公元十六世纪开始,我国的金属锌通过东印度公司输入欧洲。十八世纪三十年代英人Issac Lawson来中国考察并学习了炼锌技术。1738年William Champion取得炼锌专利,于1740年在英国Bristol建厂生产。
Brass, copper-zinc alloy, was first appeared in China about 2,400—2,000 BC. But zinc smelting began much later. This is because zinc is a rather active element, when calamine is reduced by charcoal, zinc vapor thus obtained is easily oxidized by air or carbon dioxide.The key to obtain metallic zinc in ancient times lay in finding a suitable inner receptacle to quickly condensc its vapor. In Ming dynasty,and perhaps much earlier, China solved this problem and produced a large quantity of zinc. It appears tha...
