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

5 FAQs of Boron Nitride/BN Ceramic Tube/Cylindrical Shape Ceramic

Boron nitride (BN) ceramic tubes are advanced materials used in high-temperature and electrical insulation applications. Here are five common questions about BN ceramic tubes. What is boron nitride ceramic? Boron nitride ceramic is a synthetic material made from boron and nitrogen atoms. It has a hexagonal crystal structure similar to graphite. BN ceramic works well in extreme conditions due to high thermal stability and chemical resistance. It is often used as a substitute for metals or other ceramics in demanding environments.

What are the main uses of BN ceramic tubes? BN ceramic tubes handle high-temperature processes like semiconductor manufacturing, metal casting, and aerospace components. They serve as crucibles, insulators, or protective sleeves. Their non-reactive nature makes them ideal for molten metal containment. They also function in vacuum systems due to low outgassing.

How does BN ceramic perform under heat? BN ceramic withstands temperatures up to 3000°C in inert atmospheres. It has excellent thermal shock resistance, meaning it can cool or heat rapidly without cracking. Its thermal conductivity is higher than most ceramics but lower than metals. This balance helps manage heat distribution in applications like furnace parts.

Is BN ceramic electrically insulating? Yes. BN ceramic is an electrical insulator even at high temperatures. It does not conduct electricity, making it safe for electronic components or high-voltage equipment. Its insulation properties stay stable across temperature changes, unlike some materials that degrade.

How do you maintain BN ceramic tubes? BN ceramic tubes require minimal maintenance. Avoid mechanical impacts to prevent chipping. Clean them with non-abrasive methods like ultrasonic cleaning or mild solvents. Do not expose them to strong acids or alkalis for long periods. Store them in dry environments to prevent moisture absorption. Custom sizes or shapes are available for specific industrial needs.
