Product Overview
Boron Nitride 99% Extra Pure is a synthetically derived ceramic material renowned for its exceptional thermal stability, lubricating properties, and chemical inertness. This high-purity grade ensures minimal impurities, making it suitable for demanding applications where consistency and performance are critical. Unlike traditional lubricants, boron nitride maintains its structural integrity at extreme temperatures (up to 2000°C in inert atmospheres), resisting oxidation and thermal shock. Its hexagonal crystal structure provides a low coefficient of friction, reducing wear in mechanical systems without reacting with most acids, alkalis, or molten metals. The powder form allows for easy dispersion in composites, coatings, or as a standalone dry lubricant. Its high thermal conductivity (parallel to its layers) further enhances heat dissipation in electronic and industrial applications. Whether used as a release agent, refractory additive, or thermal interface material, this boron nitride grade delivers reliability in environments where conventional materials fail.
FAQs
1. What is the maximum operating temperature for this boron nitride?
It remains stable up to 2000°C in inert or reducing atmospheres and approximately 850°C in oxidative environments.
2. Can this be used as a substitute for graphite in lubrication?
Yes, it offers similar lubricating properties but with superior chemical resistance and higher temperature tolerance compared to graphite.
3. Is this grade compatible with molten metals like aluminum?
Yes, its chemical inertness prevents reactions with molten aluminum, magnesium, and other non-ferrous metals.
4. How should this powder be stored to maintain purity?
Store in a sealed container in a dry, cool environment to prevent moisture absorption, which can affect its performance.
5. Does this boron nitride conduct electricity?
No, it is an electrical insulator, unlike graphite, making it suitable for applications requiring thermal conductivity without electrical conduction.
