Pyrolytic Boron Nitride (PBN) is a high-purity ceramic material with exceptional thermal conductivity (400W/mK), electrical insulation, and chemical inertness for extreme temperature applications up to 2000°C.
Product Overview
Pyrolytic Boron Nitride (PBN) is a high-performance, specialty ceramic material produced through a unique pyrolytic deposition process. This process deposits hexagonal boron nitride "snowflakes" layer by layer on a substrate, creating products with exceptional high-temperature stability, excellent electrical insulation, and superior corrosion resistance. PBN is widely used in high-temperature, high-pressure, and corrosive environments, particularly in the semiconductor, metallurgy, and high-temperature vacuum industries.
Features
