XTL sintyron 99.999% pbn pyrolytic boron nitride vgf crucible

pyrolytic boron nitride is an excellent electrical insulator with excellent lubricity and high temperature stability, maintaining its lubricity and inertia even at extremely high temperatures. The mechanical properties of boron nitride are relatively poor, but it has a high heat capacity, excellent thermal conductivity, outstanding dielectric strength and ease of processing. In an inert atmosphere, boron nitride can withstand high temperatures of more than 2000 ° C, so it is an ideal high-temperature thermal insulation material.
