Overview of Boron Nitride Ceramic Bn Round Sheet with Excellent Thermal Shock Resistant

Boron Nitride Ceramic Bn Round Sheet with Excellent Thermal Shock Resistant ceramics are a class of advanced technical ceramics, often referred to as “white graphite.” They are renowned for their unique combination of properties, including high thermal conductivity, excellent electrical insulation, and outstanding thermal shock resistance. Available in various forms such as hot-pressed solids, coatings, and composites, BN ceramics are critical in demanding applications across aerospace, electronics, and metallurgical industries.

Features of Boron Nitride Ceramic Bn Round Sheet with Excellent Thermal Shock Resistant

• High Thermal Conductivity: Offers excellent heat dissipation, similar to metals, while maintaining electrical insulation.

• Excellent Thermal Shock Resistance: Withstands extreme and rapid temperature changes without cracking.

• Superior Electrical Insulation: Maintains high resistivity even at elevated temperatures.

• Low Dielectric Constant and Loss: Ideal for high-frequency and microwave applications.

• Good Chemical Inertness: Resists attack from most molten metals, slags, and salts.

• Non-wetting and Non-reactive: With many molten metals like aluminum and copper.

• High Temperature Stability: Can be used in inert or vacuum atmospheres up to 3000°C.

• Machinability: Can be precision-machined into complex shapes using conventional tools, unlike many other advanced ceramics.

Specifications of Boron Nitride Ceramic Bn Round Sheet with Excellent Thermal Shock Resistant

This boron nitride ceramic round sheet handles extreme heat changes easily. It won’t crack or break when temperatures shift fast. That thermal shock resistance makes it very reliable in tough conditions.

The material is pure boron nitride. It offers high thermal conductivity. Heat moves through it quickly and evenly. This helps prevent hot spots. The sheet performs well up to very high temperatures in air. In inert gas or vacuum, it withstands even more heat.

Electrical insulation is another key feature. Boron nitride doesn’t conduct electricity. This is vital for many electrical and electronic uses. The material is also chemically inert. It resists attack from most molten metals and salts. Acids and alkalis generally don’t affect it. It won’t wet by glass or aluminum.

Mechanical strength is good. The sheet provides solid support. Its hardness is moderate. This allows for easier machining compared to some other ceramics. You can drill it or cut it to specific sizes. The surface stays smooth after machining.

Available diameters range widely. Common sizes are from 50mm up to 300mm or more. Thickness options are also flexible. Typical thicknesses might be 1mm, 3mm, 5mm, or 10mm. Other sizes are possible. The sheet is usually white or off-white. Its density is relatively low for a ceramic. This makes handling easier.

Applications of Boron Nitride Ceramic Bn Round Sheet with Excellent Thermal Shock Resistant

Boron nitride ceramic round sheets are special. They look like graphite but are much tougher. White graphite is another name for them. These sheets handle extreme heat changes without cracking. This thermal shock resistance is key. They work where other materials fail.

Heat management is a big use. These sheets go under high-power electronics. They pull heat away fast. This keeps circuits cool and reliable. Semiconductor manufacturing relies on them. They hold wafers during high-temperature processes. The heat doesn’t damage the sheet or the wafer.

Metal casting uses them too. They form liners for crucibles holding molten metal. Pouring hot metal into a cold mold creates huge stress. Boron nitride sheets survive this. They don’t crack or contaminate the metal. Foundries need this reliability.

High-temperature furnaces need protection. These sheets act as shields or setters. They protect furnace walls from direct heat and spills. They also hold parts being heated. The sheets withstand repeated heating and cooling cycles. This durability saves money.

Plasma applications demand tough materials. Boron nitride round sheets work well here. They serve as insulators and components in plasma systems. The intense heat and energy don’t break them down. Aerospace and research labs use them.

The material doesn’t stick to most molten metals or glasses. This non-wetting property is valuable. Glassmakers use the sheets during forming. Molten glass slides off easily. This prevents defects and eases production.

Boron nitride is also an electrical insulator. This adds another layer of usefulness. It safely separates electrical parts in hot environments. Combining insulation with heat resistance is powerful. Industries like automotive and energy benefit.

These round sheets offer a unique mix. Excellent thermal shock resistance is the main feature. They enable processes other materials can’t handle. Their reliability improves efficiency and product quality across many demanding fields.

5 FAQs of Boron Nitride Ceramic Bn Round Sheet with Excellent Thermal Shock Resistant

Here are 5 FAQs about Boron Nitride Ceramic BN Round Sheets with Excellent Thermal Shock Resistance:

What is Boron Nitride Ceramic? It’s a special material. People call it “white graphite”. It looks similar. It acts very different. Boron Nitride handles extreme heat well. Heat moves through it fast. It doesn’t stick to most metals or glass. This makes it very useful.

Why is thermal shock resistance important? Things break when temperatures change fast. Hot to cold quickly stresses materials. Cracks happen. Boron Nitride sheets resist this stress extremely well. Sudden big temperature changes don’t harm them. This reliability matters in tough jobs.

How hot can these sheets get? They handle very high temperatures. In air, they work fine up to about 900 degrees Celsius. In vacuum or special gases, they go much higher. Over 2000 degrees Celsius is possible. They stay stable. They don’t melt or degrade easily.

Where are these round sheets used? They fit many demanding jobs. People use them in high-temperature furnaces. They are good for metal casting. Semiconductor processing needs them. They work for welding and brazing fixtures. Aerospace applications rely on them. Anywhere heat changes fast, they help.

Are there handling precautions? Yes, handle them carefully. They are strong but can be brittle. Avoid sharp impacts. Don’t drop them. Use appropriate cutting tools. Follow the supplier’s specific guidelines. This prevents damage before use.
