Boron Nitride Nozzle (BN Nozzle) Description

Boron Nitride Nozzles are high-performance ceramic components made primarily from hexagonal boron nitride (hBN) or its advanced composites such as Hot-Pressed Boron Nitride (HPBN). These nozzles are engineered for demanding applications that require excellent thermal resistance, chemical stability, and non-reactivity with molten metals and slags.

Key Features:

• Exceptional Thermal Resistance: Withstand temperatures up to 2000°C in inert or vacuum environments.
• Non-Wettability: Do not react with or adhere to molten metals such as aluminum, magnesium, and copper.
• Excellent Machinability: Easily machined to precise dimensions and complex geometries.
• High Electrical Insulation: Maintain insulating properties even at elevated temperatures.
• Corrosion Resistance: Chemically stable in aggressive atmospheres and molten metal environments.
