HDA series are high-density Boron Nitride agglomerated particles. The tap density can reach 0.7g/cm3. The products contain single crystal Boron Nitride which is compacted and densified to materials with very low porosity. At present, HDA series comes in two specifications. One is a larger agglomerate with increased Boron Oxide content and  D₅₀ of about 210 μm. Another one is smal agglomerated product with low Boron Oxide content and  D₅₀ of about 22 μm.

GR series are medium density granulated Boron Nitride particles with a tap density of 0.4 to 0.6 g/cm3. GR series is spheroidal grade, of laminated particles of high-purity and high crystallinity Boron Nitride single crystals. The typical particle size varies from 50 ~360 μm to fit for different applications.
