Boron Nitride Powder (BN) is a high-performance ceramic material known for its unique combination of properties, including excellent thermal conductivity, high electrical insulation, and superior chemical stability. This compound is widely used in various industries such as electronics, aerospace, and manufacturing, where it serves in critical components exposed to demanding environments. Its unique chemical composition and properties make it ideal for applications requiring reliability, durability, and high performance.
Product Overview
Boron nitride (BN) is a refractory compound made of boron and nitrogen, known for its excellent heat resistance and chemical stability. It exists in two major forms: hexagonal (h-BN) and cubic (c-BN). Hexagonal boron nitride offers excellent lubrication and chemical inertness, while cubic boron nitride, which is second only to diamond in hardness, boasts outstanding wear resistance and high thermal conductivity. BN is widely used in high-temperature, wear-resistant, and corrosion-resistant environments.
Product Features
- High Hardness and Wear Resistance:Cubic boron nitride (c-BN) is one of the hardest known materials, ideal for wear-resistant coatings and cutting tools.
- Excellent Chemical Stability:BN is chemically inert and resists corrosion from most chemicals, making it suitable for harsh environments.
- Outstanding Thermal Conductivity:Especially cubic boron nitride, which has a high thermal conductivity, making it suitable for high-temperature applications.
- High Dielectric Strength and Volume Resistivity:BN performs excellently in electrical insulation and electronic applications due to its high dielectric breakdown strength and volume resistivity.
- Excellent Lubrication:Hexagonal boron nitride (h-BN) provides exceptional lubrication properties, especially in high-temperature environments.
Applications
- Wear-Resistant Coatings:Due to its high hardness and wear resistance, BN is widely used in wear-resistant coatings.
- Electrical Insulators:With excellent dielectric breakdown strength and high volume resistivity, BN is commonly used in electrical insulation materials.
