This is titanium sponge that comes out of the bottom of this reactor, and it subsequently re-melted in a vacuum arc furnace.
海绵状的钛,从反应器的底部出来，随后在真空炉中重新熔炼。
-
Earlier this summer I was at a smelter in Japan, the largest titanium smelter on the planet.
早在这个夏天我去了日本一家熔炼厂，那是全世界最大的熔炼厂。
-
So the correct answer for titanium plus two Ar3d2 is going to be argon 3 d 2, whereas if we did not rearrange our order here 4s2 we might have been tempted to write as 4 s 2 so keep that in mind when you're doing the positive ions of corresponding atoms.
所以正2价钛离子,的正确答案是，然而如果我们不重新安排顺序,我们可能会写出2,所以请记住,它当你们在解关于原子,的正离子的时候。
-
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。
-
And so, for that, I want to look at the production of titanium by the Kroll process.
因此而言，我想看看克劳尔法,制备钛的工艺。
-
And then, that produces 515 moles titanium.
嗯，就是产生了515摩尔的钛。
-
And, these are giant billets of solid titanium weighing tens of tons.
这些巨大的固体钛的铸锭,有十几吨。
-
And, this is a really clever reaction because titanium tetrachloride is a gas.
这是一个非常巧妙的反应,因为四氯化钛是一种气体。
-
How do we know that mag will reduce titanium tetrachloride?
我们如何知道,镁会还原四氯化钛？
-
While he was still in Luxembourg, just before World War II broke out, he emigrated to the United States and finished his career in the Pacific Northwest where he helped make huge quantities of titanium.
他一直住在卢森堡，在二次世界大战爆发前，他移民到了美国,后半生在太平洋西北部,他制备了大量的钛结束了他的事业。
-
I could make it out of titanium if I wanted.
也可用钛，如果我想的话。
-
Nobody says titanium tetrachloride.
没人会称之四氯化钛。
-
So, for example, if we needed to figure out the electron configuration for titanium, 4s2 it would just be argon then 4 s 2, 3d2 and then we would fill in the 3 d 2.
所以举个例子,如果我们需要解出钛的电子构型，它会是Ar然后，然后我们填充。
-
I can only make as much titanium as is consumed by the available magnesium.
有多少可以被消耗的镁,就能得到相应的钛。
-
You have salt on top, and you have titanium on the bottom.
这时盐在上面，金属钛沉在下部。
-
So, how much titanium can I make?
我能制出多少的钛呢？
-
And then I convert that to mass, and that gives me 24.7 kg of titanium.
换算成质量，就是24。7kg的钛。
-
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.
四氯化钛和镁,反应生成氯化镁和钛,1937年W。J。克劳尔发明了这个方法。
-
I don't care how you do it on exams or on problem sets, but you do need to be aware that the 3 d once filled is lower in energy than the 4 s, and the reason you need to be aware of that is if you're asked for the electron configuration now of the titanium ion.
我不关心你们在考试或者,问题集中如何做它，但是你们的确需要知道3d一旦被填充,它的能量是小于4s的，你们需要知道这个的原因,是如果你现在被要求,写出钛离子的电子构型。
