Boron Nitride Plate, Boron Nitride Sheet (H-BN)
Boron Nitride Plate or Boron Nitride Sheet, also known as h-BN plate or sheet, is a high-performance ceramic material made from boron and nitrogen. It has excellent thermal stability, high electrical insulation, low dielectric constant, and high mechanical strength. The plate or sheet is made by pressing and sintering boron nitride powder, which results in a dense, uniform, and smooth surface.
Boron Nitride Plate or Sheet has a wide range of applications, including:
-
High-temperature insulation: It can withstand temperatures up to 2200°C without melting or decomposing, making it an ideal material for high-temperature insulation in furnaces, heaters, and other industrial applications.
-
Electrical insulation: Boron Nitride Plate or Sheet has excellent electrical insulation properties and can be used as an insulating material for electronic components, high-voltage equipment, and insulators.
-
Mold release: Due to its low coefficient of friction, Boron Nitride Plate or Sheet is an excellent mold release agent for use in the casting of metals, plastics, and other materials.
-
High-temperature lubrication: Boron Nitride Plate or Sheet is an excellent dry lubricant for use in high-temperature environments where other lubricants would break down.
-
Aerospace and defense: Boron Nitride Plate or Sheet is used in aerospace and defense applications due to its excellent thermal stability, electrical insulation, and low outgassing properties.
Boron Nitride Plate or Sheet is available in a variety of thicknesses and sizes and can be customized to meet specific requirements.
