The advantages of using boron nitride powder in thermal insulation materials and partitioning powder include:
Excellent thermal conductivity: Boron nitride exhibits extremely low thermal conductivity, effectively inhibiting heat conduction. This makes it suitable for creating highly efficient thermal insulation materials, aiding in temperature stability.
Chemical stability: Boron nitride demonstrates good chemical stability at high temperatures, resisting oxidation, corrosion, and other forms of degradation, thereby ensuring long-term usage.
High-temperature resistance: Boron nitride maintains structural stability even in high-temperature environments, making it suitable for insulation requirements in high-temperature settings, such as thermal protection in aerospace applications.
Abrasion and corrosion resistance: Boron nitride possesses good abrasion and corrosion resistance, leading to a longer service life and sustained insulation effectiveness in complex environments.
Lightweight: Boron nitride is relatively lightweight compared to some traditional insulation materials, reducing structural burden and enhancing ease of application.
