Specifications of High Purity White Boron Nitride Hbn Bn Ceramic Sheet

This High Purity White Boron Nitride (HBN/BN) Ceramic Sheet delivers exceptional performance for demanding applications. It boasts a minimum boron nitride purity of 99%. This guarantees consistent material quality. The sheet offers excellent thermal conductivity. It carries heat away very effectively. Its electrical insulation remains strong even at high temperatures. This prevents unwanted current flow. The material withstands extremely high temperatures easily. It handles harsh chemical environments well. Acids and alkalis cause minimal damage.

The sheet provides low thermal expansion. It resists cracking under sudden temperature changes. Its surface feels smooth and slippery. This reduces friction during use. Machining the sheet is straightforward. You can cut it to specific sizes easily. Common thicknesses are 0.5mm, 1.0mm, and 2.0mm. Custom sizes are also possible. Standard sheet dimensions are 200mm x 200mm or 300mm x 300mm. Larger sizes can be requested.

This BN sheet excels in thermal management. It works well as a heat spreader or insulator. Its high dielectric strength suits electrical insulation needs. The material acts as a barrier in molten metal handling. It functions reliably in high-temperature furnaces. Crucibles and boats benefit from its non-wetting properties. It releases parts cleanly in sintering processes. The sheet is inert and safe for semiconductor production. It finds use in aerospace components too. Vacuum systems utilize its stability.

Applications of High Purity White Boron Nitride Hbn Bn Ceramic Sheet

High purity white boron nitride ceramic sheets solve tough problems in demanding industries. This advanced material handles extreme heat exceptionally well. It withstands temperatures soaring past 2000°C without breaking down. This makes it perfect for high-temperature furnaces. BN sheets line crucibles holding molten metals. They protect sensitive furnace parts. The material also resists chemical attack. Acids and bases don’t damage it easily. This chemical stability is vital for harsh processing environments.

Thermal management is a major strength. Heat flows through BN sheets very efficiently, much faster than steel. But electricity doesn’t pass through them at all. This unique combination is ideal for electronics. BN sheets cool powerful computer processors. They insulate high-voltage components safely. Manufacturers use them under semiconductor wafers during intense heating steps. The material remains stable and reliable.

The metallurgy industry relies heavily on BN sheets. They form release layers between molten aluminum and its container. Molten metal won’t stick to the smooth BN surface. This prevents contamination and allows easy removal of cast parts. Foundries get cleaner results and longer equipment life.

Cosmetic companies use ultra-fine BN powder derived from these sheets. It gives makeup a smooth, silky feel. The powder helps products spread evenly on skin. It also absorbs excess oil effectively. BN is chemically inert and safe for skin contact. Its whiteness ensures no color change in cosmetics.

Handling these sheets is straightforward. They machine easily into precise shapes using standard tools. Their high purity means no harmful additives leach out. BN sheets offer consistent performance batch after batch. Engineers trust them for critical applications needing reliability under stress. This material delivers where others fall short.

5 FAQs of High Purity White Boron Nitride Hbn Bn Ceramic Sheet

What exactly is high purity white boron nitride ceramic sheet?
This is a specialized ceramic material. It comes in thin, flat sheets. Manufacturers make it from pure boron and nitrogen atoms. The result is a white, smooth solid. People often call it white graphite. It looks similar but performs very differently.

What are the main benefits of using this BN sheet?
Its heat management is outstanding. The sheet moves heat away very fast. This prevents overheating in electronics and tools. It also withstands extreme temperatures well. Lubrication is another key plus. Parts slide easily against it, reducing wear. Chemical resistance is strong too. Harsh acids and bases rarely damage it.

How much heat can this ceramic sheet handle?
Its temperature tolerance is very high. The sheet stays stable in air up to about 900°C (1652°F). In vacuum or inert gas, it goes much higher. Think roughly 2000°C (3632°F). This makes it perfect for furnaces and high-heat processes. It won’t melt or break down easily.

Does it conduct electricity?
No, it acts as an insulator. Electricity cannot flow through it. This is crucial for electrical insulation. Use it between live components safely. Its high thermal conductivity works alongside this. Heat escapes fast while electricity stays blocked. This combination is rare and valuable.

Are there any special handling needs?
Handle it with reasonable care. The sheet is brittle like many ceramics. Avoid dropping it or heavy impacts. Cutting requires diamond tools or lasers. Ordinary saws won’t work well. Keep it clean and dry before use. Store it flat to prevent warping or cracks.
