身份倍增一跃变为“国防金属”1808年,英国化学家戴维第一个发现了质地奇怪的镁。过了23年,法国化学家彪西改进了制镁方法。他从食盐中提取氯化镁作原料,与金属钾一同放在石英管中加热,得到份量较多的镁块。但是,镁仍然被人认为是无用的东西,长期找不到固定的“职业”。第一次 Identity doubled into “national defense metal” 1808, the British chemist David discovered the strange texture of magnesium. After 23 years, French chemist Bu Si improved the method of making magnesium. He extracted from the salt of magnesium chloride as raw material, together with the metal potassium in the quartz tube heating, get more weight magnesium blocks. However, magnesium is still considered to be useless things, long-term can not find a fixed “occupation.” the first time
