Transparent ceramics make super-hard windows

Scientists have synthesized the first transparent sample of a popular industrial ceramic. The result is a super-hard window made of cubic silicon nitride that can potentially be used under extreme conditions like in engines. Cubic silicon nitride (c-Si3N4) forms under high pressure and is the second hardest transparent nanoceramic after diamond but can withstand substantially higher temperatures.
