Spherical Boron Nitride ceramic for thermal conductivity material
Product Description
Spherical boron nitride has thermal isotropic properties, which overcomes the disadvantages of the thermal anisotropy of flake boron nitride, and can achieve good planar thermal conductivity at a lower filling ratio. It has the advantages of low density and low dielectric constant of boron nitride itself. At the same filling amount, the thermal conductivity of spherical boron nitride is more than 3 times that of flake boron nitride. Of course, we also supply boron nitride in sheets.
