As raw materials or fillers, it is widely used in metallurgy, electronic components, aerospace, boron nitride ceramics, lubricants, coatings, thermal conductivity, cosmetics and other fields.
1. What are the types of Boron Nitride Powder?
There are several types, but the two most common are:
·Hexagonal Boron Nitride (h-BN): Known for its lubricating and thermal management properties.
·Cubic Boron Nitride (c-BN): Second only to diamond in hardness, used in cutting and grinding tools.
2. What are the key properties of Boron Nitride Powder?
·High thermal conductivity
·Excellent electrical insulation
·Chemically inert
·Low friction coefficient (lubricant properties)
·High temperature resistance
3. How is Boron Nitride Powder produced?
It is synthesized through processes like chemical vapor deposition (CVD) or high-temperature reactions involving boron compounds and nitrogen sources.
4. What makes Boron Nitride Powder a good thermal conductor?
The hexagonal structure of Boron Nitride allows efficient heat transfer, making it ideal for thermal management in electronic devices.
5. Is Boron Nitride Powder safe?
Boron Nitride Powder is considered non-toxic and safe to use. However, handling should include proper protective measures, such as masks and gloves, to avoid inhalation of fine particles.
6. How does Boron Nitride Powder compare to graphite as a lubricant?
Unlike graphite, Boron Nitride Powder remains effective as a lubricant in vacuum and high-temperature environments, where oxygen is absent.
