High purity boron nitride powder

Boron nitride (BN) powder is a material with unique properties, mainly divided into structural forms such as hexagonal boron nitride (h-BN) and cubic boron nitride (c-BN). Among them, hexagonal boron nitride is the most common form, with a layered structure similar to graphite.
-Physical properties: Boron nitride powder has high thermal conductivity, low thermal expansion coefficient, excellent thermal shock resistance, high temperature electrical insulation, and low friction coefficient. It can stably exist in air up to 900 ℃ and even withstand high temperatures of 2800 ℃ in inert gases.
-Chemical properties: Stable in chemical properties, almost does not react with acids or bases, and is chemically inert to molten metals.
-Preparation methods: Common preparation methods include high-temperature and high-pressure synthesis, chemical vapor deposition (CVD), and self propagating high-temperature synthesis.
