  1. But the vaporization of magnesium suggested an alternative method : we could seal a piece of magnesium and some powdered boron inside a tantalum vessel, which is inert, and subject them to a temperature high enough to melt but not to boil the magnesium ( say, 950 degrees c )

    不過,鎂的汽化卻也啟發了另一種方法:我們可以將鎂及一些粉狀的硼密封在鉭瓶中(鉭為惰性元素) ,然後將它們加熱至足夠的溫度(例如950 ) ,使得鎂呈現熔化但尚未沸騰的狀態。
