Overview of Boron Nitride Ceramic

Boron Nitride (BN) ceramic is a unique material renowned for its exceptional properties, making it highly valuable in various industrial applications. It exists in multiple forms, primarily hexagonal boron nitride (h-BN), cubic boron nitride (c-BN), and wurtzite boron nitride (w-BN). Hexagonal BN, the most common form, is often compared to graphite due to its lubricious and thermally conductive yet electrically insulating nature. Boron Nitride ceramics are synthesized under high temperatures and pressures, offering a rare combination of properties not found in many other materials.

Features of Boron Nitride Ceramic

Thermal Conductivity: Excellent thermal conductivity, especially in the hexagonal form, allowing efficient heat dissipation.

Electrical Insulation: Outstanding electrical insulation properties make it ideal for electrical applications requiring thermal management.

Chemical Stability: Highly resistant to chemical attacks, including strong acids and bases, ensuring durability in harsh environments.

Thermal Shock Resistance: Superior resistance to thermal shock, enabling it to withstand rapid temperature changes without cracking.

Mechanical Strength: Good mechanical strength at both room and elevated temperatures, although this can vary with the form of BN.

Lubricity: Self-lubricating property due to its layered structure, which reduces friction and wear in moving parts.

Non-Toxic: Safe to use in various settings, including medical and food processing industries, due to its non-toxic nature.

High-Temperature Performance: Maintains stability at extremely high temperatures, exceeding 1000°C in inert atmospheres, making it suitable for refractory applications.

Specification of Hot Pressed BN Boron Nitride Ceramic Parts Nozzle

Hot Pressed BN Boron Nitride Ceramic Parts Nozzles offer high-performance solutions for extreme industrial environments. These nozzles are made from pure boron nitride powder processed under high heat and pressure. The result is a dense, durable ceramic material with exceptional thermal and chemical stability.

The material withstands temperatures up to 1800°C in inert atmospheres. It maintains structural integrity even under rapid temperature changes. Boron nitride ceramics show low thermal expansion, reducing stress cracks during heating or cooling. The nozzles provide excellent electrical insulation, making them safe for high-voltage applications.

These components resist corrosion from molten metals, salts, and acids. They are non-reactive to most chemicals, ensuring long service life in harsh conditions. The smooth surface finish minimizes friction, allowing efficient material flow through the nozzle. This reduces wear and prevents clogging during continuous operation.

Hot pressed BN nozzles come in custom shapes and sizes. Standard diameters range from 1 mm to 50 mm. Wall thickness varies based on application requirements. The material is machinable to precise tolerances using diamond tools. This flexibility supports complex designs for specialized industrial processes.
