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 High Purity Boron Nitride BN Powder 99% 3-5 Um for Advanced Ceramic and Solid Lubricant Applications

High Purity Boron Nitride BN Powder 99% 3-5 Um is a specialized material designed for advanced ceramic and solid lubricant applications. The powder has a purity level of 99%, ensuring minimal impurities for consistent performance. Its particle size ranges between 3 and 5 micrometers, providing optimal balance between surface area and handling properties. This makes it suitable for precision processes requiring fine material control.

The powder excels in high-temperature environments due to its exceptional thermal stability. It maintains structural integrity at temperatures up to 2000°C in inert atmospheres. This property is critical for advanced ceramics used in aerospace, electronics, and industrial heating systems. The material resists thermal shock, reducing cracking or degradation under rapid temperature changes.

Chemical inertness is another key feature. The powder does not react with acids, alkalis, or molten metals. This makes it ideal for corrosive environments, such as crucibles or linings in metal casting. Its non-toxic nature ensures safe handling in manufacturing settings.

As a solid lubricant, boron nitride powder offers low friction coefficients even under extreme conditions. It performs reliably in vacuum or high-pressure environments where liquid lubricants fail. Applications include coatings for bearings, molds, and machinery parts requiring wear resistance. The powder’s white color and smooth texture prevent contamination in sensitive processes.

Electrical insulation properties add versatility. The material does not conduct electricity, making it useful in substrates or components for electronic devices. It dissipates heat efficiently, protecting circuits from overheating.

Production processes use advanced synthesis methods to ensure uniformity. Each batch undergoes rigorous testing for particle size distribution, purity, and moisture content. This guarantees consistency for industrial users.

Packaging options include moisture-resistant containers to preserve quality during storage. Custom quantities are available for small-scale research or large-volume manufacturing.

High Purity Boron Nitride BN Powder meets global standards for industrial materials. It is widely adopted in sectors prioritizing reliability under demanding conditions. Users benefit from enhanced product longevity and reduced maintenance costs.

Applications of High Purity Boron Nitride BN Powder 99% 3-5 Um for Advanced Ceramic and Solid Lubricant Applications

High purity boron nitride (BN) powder 99% with a particle size of 3-5 micrometers serves critical roles in advanced ceramics and solid lubricant applications. This material combines unique properties like high thermal stability, chemical inertness, and exceptional lubricity. Its performance makes it ideal for demanding industrial environments.

In advanced ceramics, BN powder acts as a key additive. It enhances mechanical strength and thermal shock resistance in ceramic composites. Ceramic components made with BN withstand extreme temperatures above 2000°C. This suits them for furnace linings, crucibles, and high-temperature insulators. BN’s low thermal expansion reduces cracking under rapid temperature changes. It also improves machinability in sintered ceramics, simplifying complex shaping processes.

BN powder functions as a solid lubricant in high-temperature or vacuum conditions. Traditional oils or greases fail here. BN’s layered structure allows smooth sliding between surfaces, minimizing friction and wear. It coats metal parts in aerospace engines, reducing component degradation. BN lubricants perform reliably in environments with radiation or corrosive chemicals. They extend equipment lifespan in metalforming, electronics, and automotive systems.

The 99% purity ensures minimal impurities interfere with performance. The 3-5 micrometer particle size balances surface area and flowability. Fine particles disperse evenly in matrices, optimizing material properties. This grade meets strict standards for semiconductors and precision engineering.

BN powder supports electrical insulation in electronic ceramics. It prevents current leakage in substrates or heat sinks. Its dielectric strength remains stable across wide temperature ranges. BN-filled polymers or coatings protect circuits from overheating.

Industries value BN for reducing energy loss and maintenance costs. It enables lighter, more durable components. Its versatility drives innovation in additive manufacturing and composite materials. Manufacturers rely on BN to solve challenges in extreme operational settings.
