Aluminum and magnesium are both made by ionic liquid electrolysis, just as I showed you last day.
铝和镁都是,由离子液体电解而成,就像我昨天讲的。
And magnesium oxide has a melting point of 2,800 degrees C.
氧化镁,熔点在2800摄氏度。
So between b e, and b, between n and o, magnesium and aluminum, and then phosphorous and sulfur, what we see here is that we're kind of going down, or quite specifically, we are going down.
比如从铍到硼,从氮到氧,从镁到铝,从磷到硫,我们在这些地方看到有点下降,或者可以明确地说,我们确实在下降。
And magnesium is over a dollar a pound.
而镁是一美元一磅。
And, she loved metallurgy as I do, and she named one of her dogs Maggie, and one of her dogs Molly, magnesium and molybdenum.
她和我一样都喜欢冶金学,她给一条狗取名为麦琪,另一条取名为莫丽,镁和钼。
So, I went to the library and I looked up Advances in Molten Salt Chemistry volume six because there's an article in there about the chemistry and electrochemistry of magnesium production.
所以我去了趟图书馆,查阅了,第六版的《高级熔融态盐化学》,因为那里面有一篇关于生产镁的,化学和电化学的文章。
And at the end of the reaction, you have the reactor consumed of titanium tetrachloride magnesium.
在反应的结尾时,反应器里面,消耗了四氯化钛和镁。
Well, if we just take, for example, MgO, and let's try Mg, magnesium chloride just as an example.
我们以MgO为例,让我们试试Mg,MgCl2也是一个例。
And, seawater contains only 3.7% of the total magnesium present 7% in the Earth's crust.
而海水只含有,地表镁总量的,3。
So, clearly magnesium resources are ubiquitous and virtually inexhaustible.
所以显然镁资源是无处不在的,几乎是用之不竭的。
And, this involves the reaction of titanium tetrachloride with magnesium to form magnesium chloride plus titanium And, this was invented in 1937 by W. J. Kroll.
