Boron Nitride Composite BN-SZ Ceramic
Boron Nitride Composite BN-SZ Ceramic
Boron Nitride Composite BN-SZ Ceramic is a type of high-performance ceramic material that is made from a combination of boron nitride (BN) and zirconia (SZ) powders. It is produced through a high-temperature and high-pressure sintering process, resulting in a ceramic material with exceptional thermal and mechanical properties.
BN-SZ ceramic has a unique combination of high thermal conductivity, high electrical insulation, and excellent mechanical strength, making it a highly desirable material for a variety of industrial and electronic applications.
The addition of zirconia to boron nitride creates a composite material with enhanced mechanical strength, increased resistance to thermal shock, and improved fracture toughness. The combination of these properties makes BN-SZ ceramic ideal for use in high-temperature applications, such as heat exchangers, high-temperature furnaces, and electronic packaging.
BN-SZ ceramic is also highly resistant to chemical attack, making it an ideal material for use in harsh environments. Its exceptional electrical insulation properties make it a popular choice for electronic components, high-voltage insulators, and other electrical applications.
BN-SZ ceramic is available in a range of shapes and sizes, including plates, tubes, and custom shapes. Its properties make it a versatile material that is used in industries such as aerospace, semiconductor manufacturing, metallurgy, and automotive manufacturing.
