Boron Nitride Tubes & Rods – High Purity Ceramic Solutions for Thermal & Electrical Applications
M-Kube Enterprise offers high-purity boron nitride rods and tubes designed for advanced industrial and research applications. Our boron nitride ceramic tubes and rods are manufactured using premium hexagonal boron nitride (h-BN), known for its excellent thermal resistance, electrical insulation, and chemical inertness.
Whether you’re seeking thermal shielding in vacuum furnaces or non-wetting materials for molten metals, our BN tubes and rods deliver unmatched performance in demanding environments.
Key Features of Boron Nitride Rods & Tubes
- High-Temperature Resistance: Stable up to 2,300°C in inert atmosphere
- Excellent Electrical Insulation: Ideal for electronic and semiconductor use
- Non-Wettability: Does not react with most molten metals, especially aluminum and magnesium
- Chemical Inertness: Resistant to many acids, bases, and reactive elements
- High Purity Grades Available: Ensures consistent thermal and dielectric properties
