The result was a composite that was able to withstand twice as much pressure as unalloyed silicon nitride.

和纯相比，其合成物能经受的压力强度翻倍。

The ceramic they experimented with was silicon nitride, a material much admired in the aerospace industry.

她们测试的陶瓷材是－－一种在太空工业中饱受赞誉的材。

Components are made by sintering it in powder form in a mould, at 1,000oC, for several hours.

这些部件是将置于模具中，处于1000摄氏度高温下烧制数小时而成。

When the team examined what they had done under a microscope, they found that the graphene had wrapped itself around the silicon-nitride grains, forming continuous walls.

当研究团队在显微镜下观察合成物时，他们发现石墨烯包裹在颗粒周围，形成了连续的" 壁" 。

It's made from the stuff of microchips: silicon, a layer of silicon dioxide, and on top a very thin film of silicon nitride, which is perforated by a grid of microscopic circular holes.
