Zweigniederlassung der 3M Deutschland GmbH

3M™ is now the biggest boron carbide producer in the western world. 3M™ Boron Carbide Powders belong to the most important group of non-metallic hard materials. By virtue of the manufacturing process, 3M™ Boron Carbide Powder (previously: TETRABOR®) has a constant high purity, It contains almost the exact theoretical ratio of boron to carbon of 4:1. 3M™ Boron Carbide Powder is available in narrow ranges of grain sizes and grain mixtures (approx. 1 to 20 000 µm). Thanks to their versatility, our powders are characterized by excellent properties, such as:

  • Extreme hardness
  • High chemical resistance
  • Outstanding heat resistance
  • High boron content


Precursor for the production of boron halides and metal borides (e.g. Boron Trichloride BCI3)
The high boron content of almost 80 % makes 3M™ Boron Carbide an inexpensive boron source.

Sintering and hot pressing powder for the manufacture of sintered boron carbide parts
3M™ Boron Carbide is ideally suited thanks to its high chemical purity and constant delivery quality. It has virtually the theoretical density of 2.51 kg/m3

Filler for polymers, metals, concrete, etc.
For absorption and particle reinforcement

Constituent of electrode materials for wear protection
The extreme hardness of TETRABOR® boron carbide (9.5+ N/mm2 Mohs scale) makes it ideally suited for wear protection in welding and thermal spraying.
