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.

These bushings work well in high-temperature settings like metal handling, glass molding, and aerospace components. They manage thermal shock without fracturing, preserving structural integrity under rapid temperature shifts. The product withstands rust from molten steels, salts, and acids, making it appropriate for chemical sectors. Electric insulation properties protect against current leakage in high-voltage equipment.

The hexagonal BN framework develops a self-lubricating surface, getting rid of the need for exterior lubricants. This reduces maintenance prices and downtime. The sleeves fit into revolving or moving equipment components, providing smooth procedure under heavy loads. Common uses consist of heating system components, welding devices, and semiconductor manufacturing tools.

Requirement sizes range from 5mm to 200mm in internal diameter, with personalized measurements readily available. Wall surface thickness varies between 1mm and 20mm, balancing stamina and weight. The BN finish thickness is commonly 10-50 microns, used by means of plasma spray for uniform adhesion. Surface area roughness stays below 0.8 micrometers, decreasing friction-induced heat.

Tons capacity depends on dimension and wall density, sustaining up to 150 MPa compressive anxiety. The product’s reduced thermal development coefficient guarantees dimensional stability across temperature varieties. Setup is uncomplicated as a result of precise machining resistances, frequently within ± 0.01 mm. Compatibility with steels and ceramics allows combination into existing systems without galvanic deterioration risks.

Hexagonal Borazon BN bush sleeves operate in vacuum cleaner environments without outgassing, crucial for aerospace and electronics. They exceed conventional products like graphite or steel alloys in lifespan and reliability. Marginal debris generation maintains equipment clean, lowering contamination in delicate processes. Customizable choices consist of threaded inserts, flanged styles, or grooved surfaces for specific applications.
