It is very soft and is a good lubricant, and it is also very lightweight. And it is highly stable at room temperature and atmospheric pressure. Nanocomposites prepared with hexagonal boron nitride interact with light and heat in unexpected ways, which could be useful for next-generation microchips, quantum devices, and other advanced technological applications. What we want to investigate is whether the discharge plasma sintering technology can independently improve the quality of hexagonal boron nitride, or whether composite materials are needed to achieve this effect. This will enable hexagonal boron nitride to have a wider range of customized mechanical, thermal, electrical, and optical properties.
