The best we've got is a compound called tantalum carbide, which can handle about 4,000 degrees Celsius max.

我们好材料是一种叫做碳化化合，它可以承受 4000 摄氏度温度。

2 mm in diameter. Tantalum, haven't got a clue what it's used for.

直径0.2毫米。，完全不知道它有什么用途。

Tantalum is an element that's derived from an ore called columbite-tantalite, or coltan.

是一种元素，源自一种叫做钶铁矿或钶铁矿矿石。

This is a tantalum capacitor. Or at least we think it's a tantalum capacitor.

这是一个电容。或者至少我们认为它是一个电容器。

Metals such as copper or tantalum, insulators which are typically called oxides, and crystalline layers of silicon.

如铜或等金属、通常称为氧化缘体，以及硅晶体质层。

Tantalum is highly sought after because it's got a very high melting point and it resists corrosion.

之所以备受追捧，是因为它具有非常熔点并且耐腐蚀。

The recovery of tin was recently added, says Mr Bormann, with zinc, gallium and tantalum planned for next year.

博尔曼先生说，近又增加了锡回收，并计划明年增加锌、镓和回收。

That is possible because this part of the transistor is made of tantalum pentoxide, a material whose atoms are arranged in a lattice which contains holes large enough for copper atoms to squeeze through.

这是有可能实现，因为这部分晶体管是由五氧化二制造——这种材料可以将它自身原子排布在晶格中，这些晶格包括一些足够大孔，可以让铜原子挤过去。
