High-quality pure BN powder with different particle sizes for the production of boron nitride ceramics, as high temperature lubricant or as thermal conductive filler. 

Due to its special particle shape, spherical BN (XSBN series) has thermal isotropic properties that overcome the disadvantage of the thermal anisotropy of BN and achieve a high homogeneous thermal conductivity even with a low filling level. With the same filling quantity, spherical BN can have three times the thermal conductivity of normal BN.
