pyrolytic boron nitride has a long history as one of the coolest ceramics around, and the technology behind it is nothing short of impressive. The gist of it is that PBN uses chemical vapor deposition (CVD) to create thin and strong crystalline boron nitride microchips, or chips for short, of all shapes and sizes. Specifically, the material is produced by combining oxygen with boron nitride and other gaseous precursors in a controlled environment. The result is a ceramic that can boast of some serious properties, like low thermal expansion, high heat shock resistance and high-grade electrical conductivity, all in a package that can be easily handled by humans or machines. Among the many applications, it is also known for its impressive performance in the heat and light industry, as well as its capabilities as an energy saving device. It is a common component in the manufacture of high-tech gadgets, such as mobile phones and other electronics.
