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 Heat Conductive Ceramic Boron Nitride Plate/sheet/washer

Warm Conductive Porcelain Boron Nitride Plates, Sheets, and Washers are innovative materials developed for high-performance thermal monitoring. Made from hexagonal boron nitride (h-BN), these items integrate exceptional warm conductivity with electrical insulation. They deal with extreme temperatures, resist chemical deterioration, and preserve security popular settings.

The material offers a thermal conductivity series of 15-30 W/m · K along the surface area. This permits reliable heat dissipation while preventing electrical present circulation. The dielectric toughness goes beyond 35 kV/mm, making it perfect for electronic devices needing insulation. Running temperature levels reach up to 900 ° C in air and 2000 ° C in inert gases without weakening.

Boron nitride porcelains withstand most liquified steels, acids, and antacid. They do not respond with glass or semiconductor products. This makes them ideal for metal spreading, semiconductor processing, and high-temperature heating system parts. The reduced thermal growth coefficient minimizes shape adjustments under warmth anxiety.

Offered in plates, sheets, and washers, these parts come in standard thicknesses from 0.5 mm to 50 mm. Custom shapes and sizes are feasible via machining. Surface surfaces vary from smooth to textured for certain rubbing or bonding demands.

Unlike metals, boron nitride does not conduct electricity. Compared to plastics, it deals with much greater temperatures. It outperforms alumina porcelains in thermal shock resistance. The product is machinable utilizing requirement tools, minimizing production expenses.

Typical applications include warm sinks in power electronics, crucibles for steel melting, and insulating parts in aerospace systems. They act as diffusion obstacles in semiconductor manufacturing and thermal pads in LED lights. The non-wetting surface stops bond in molten metal handling.

These products meet industrial requirements for purity and efficiency. They are without binders or ingredients that might endanger thermal properties. Marginal outgassing takes place in vacuum cleaner atmospheres.

Users take advantage of longer devices life expectancy due to minimized thermal anxiety. Upkeep prices drop as a result of chemical resistance. Energy effectiveness improves with faster warm transfer. Compatibility with varied atmospheres sustains usage in laboratories, factories, and sophisticated study.

5 FAQs of Heat Conductive Ceramic Boron Nitride Plate/sheet/washer

What is a heat conductive ceramic boron nitride plate/sheet/washer made of? It is made from boron nitride. Boron nitride is a synthetic ceramic material. It has a hexagonal crystal structure similar to graphite. This structure allows it to conduct heat well. It stays electrically insulating. The material is chemically stable. It resists most acids and molten metals. It is used in high-temperature environments.

Why choose boron nitride over metal or other ceramics? Metals conduct heat but also electricity. This is bad for electrical insulation. Other ceramics insulate electrically but lack thermal conductivity. Boron nitride combines both properties. It moves heat efficiently without conducting electricity. It handles thermal stress better than metals or alumina. It expands less when heated. This reduces cracking risks.

Where are boron nitride plates/sheets/washers used? They are common in electronics. They cool power transistors or LED modules. They separate heat sources from sensitive parts. Aerospace uses them for thermal management. Industrial furnaces use them as liners or insulators. They work in semiconductor manufacturing. Electric vehicle battery systems use them for heat spreading.

What temperature range does boron nitride handle? It works from -200°C to 1000°C. It stays stable in vacuums or inert gases. In oxygen-rich settings, it degrades above 800°C. It performs better than plastics or rubber here. It does not melt or soften.

Is boron nitride safe to handle? It is non-toxic and chemically inert. Fine dust from machining can irritate lungs. Wear masks and gloves during processing. Clean surfaces with isopropyl alcohol. Store in dry conditions to avoid moisture absorption.
