Přehled keramiky z nitridu boru

Keramika z nitridu boru (BN) je unikátní materiál známý pro své výjimečné vlastnosti, díky čemuž je vysoce cenný v různých průmyslových aplikacích. Existuje v mnoha formách, především hexagonální nitrid boru (h-BN), kubický nitrid boru (c-BN) a wurtzit nitrid boru (w-BN). Šestihranný BN, nejběžnější forma, je často přirovnáván ke grafitu kvůli jeho mazacímu a tepelně vodivému, avšak elektricky izolačnímu charakteru. Keramika z nitridu boru je syntetizována za vysokých teplot a tlaků a nabízí vzácnou kombinaci vlastností, které se u mnoha jiných materiálů nenacházejí.

Specification of Boron Nitride Ceramic BN Rod

Boron nitride ceramic BN rods are advanced commercial elements designed for high-performance applications. These poles are made from hexagonal boron nitride, a synthetic material recognized for combining properties similar to graphite with remarkable thermal and chemical security. BN poles exhibit high thermal conductivity, typically varying between 30-40 W/m · K. This permits reliable heat dissipation popular environments. They run properly in temperatures approximately 900 ° C in oxidizing environments and 2000 ° C in inert or vacuum cleaner problems. Their reduced thermal expansion coefficient guarantees dimensional stability under quick temperature level changes.

BN poles offer outstanding electric insulation, even at raised temperatures. This makes them optimal for use in digital and semiconductor industries where electrical isolation is vital. The material’s dielectric stamina exceeds 35 kV/mm, preventing electric malfunction under high voltage. Chemically, boron nitride is inert to most liquified metals, acids, and antacid. It stands up to rust from aggressive substances like liquified aluminum or glass. This chemical resistance prolongs the life expectancy of BN poles in harsh processing environments.

The mechanical properties of BN rods consist of a firmness of roughly 2 Mohs, making them machinable with common tools into complex shapes. They preserve lubricity similar to graphite, decreasing wear in moving parts. Applications cover several sectors. In semiconductor manufacturing, BN rods work as crucibles for melting high-purity products. Metallurgical processes utilize them as thermocouple sheaths or constant casting elements. Aerospace systems employ BN rods for insulation in high-temperature sensing units.

Surface area coatings can be customized from typical matte to polished surfaces for particular rubbing demands. BN poles are offered in sizes from 5 mm to 150 mm, with sizes as much as 500 mm. Personalized dimensions are achievable through precision machining. The product complies with RoHS and REACH standards, making certain ecological and security compatibility. Proper handling prevents mechanical shock to stop cracking. Storage space in completely dry problems preserves material honesty prior to use.
