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

我们最好的一种叫做碳化钽的化合物，它可以承受最约 4000 摄氏度的温度。

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

这一个钽电容。或者至少我们认为它一个钽电容器。

Tantalum wire. It's very high quality research sample.

钽丝。 这质的研究样本。

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

钽一种元素，源自一种叫做钶钽铁矿或钶钽铁矿的矿石。

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

直径 0. 2 毫米。 钽，不知道它有什么用。

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

钽之所以备受追捧，因为它具有的熔点并且耐腐蚀。

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.

这有可能实现的，因为这部分晶体管由五氧化二钽制造的——这种可以将它自身的原子排布在晶格中，这些晶格包括一些足够大的孔，可以让铜原子挤过去。

But essentially there are 3 key groups  of materials that are added or deposited onto the wafer: metals such as copper or tantalum,   insulators which are typically called oxides, and crystalline layers of silicon.

但本质上，有三组主要被添加或沉积在晶圆上：铜或钽等金属、通称为氧化物的绝缘体和硅晶体层。
