Caractéristiques de conception
Boron nitride ceramic tube sleeves (also known as ceramic structural rings) are high-performance ceramic materials primarily used in industrial applications requiring high temperature, high pressure, and excellent electrical insulation properties. Their main characteristics and application areas are as follows:
Stabilité aux hautes températures
Les céramiques de nitrure de bore peuvent conserver leur structure et leurs performances à des températures extrêmement élevées (jusqu’à 850 °C en air et 2000 °C dans des gaz inertes), ce qui les rend adaptées aux environnements à haute température.
Excellente isolation électrique
Le nitrure de bore offre une excellente isolation électrique, avec une résistivité à température ambiante pouvant atteindre 10^16 Ω·cm, garantissant la sécurité dans les applications électriques.
Conductivité thermique supérieure
Grâce à sa conductivité thermique élevée (50-70 W/(m·K)), le nitrure de bore est idéal pour les systèmes de gestion thermique, permettant d’optimiser les performances thermiques des équipements.
Faible coefficient de dilatation thermique
Le nitrure de bore présente un faible coefficient de dilatation thermique (1-1,2 x 10^-6/K), assurant une stabilité dimensionnelle lors des cycles thermiques et réduisant ainsi les problèmes de contraintes thermiques.
Inertie chimique
Le nitrure de bore est très résistant à la plupart des produits chimiques et aux environnements corrosifs, garantissant que ses performances ne soient pas altérées dans des conditions sévères.
Propriétés autolubrifiantes
Le nitrure de bore hexagonal possède un certain caractère lubrifiant, ce qui le rend adapté aux applications mécaniques requérant un faible coefficient de frottement.
