General properties & features: B4C ceramic poses high hardness just after those of diamond and cubic BN; Light weight, high module, anti-corrosion against acid and base, absorber of neutron and oxygen, good thermal conductivity. The nanopowder provides higher activity, strength and ductile.

Some applications:
1) abrasives, cutting tool, mould, bearings
2) particle coating on hard alloys, bearings, super alloys
3) nanofillers in composites of ceramics, plastics and powder metallurgy
4) refining agent in some alloys

Notes:
The nanopowder needs to avoid direct sunshine. Moisture will result for agglomerations.
