Large scale
CNT production facility
Our CARBON CIRCULAR TECHNOLOGY*
will accelerate the social
implementation of Carbon nanotubes!
* Our original combined process from sputtering,
CNTs growing to collecting
Ultra-high quality CNTs
of three forms
Caltema can produce long and
homogeneous MWCNTs by little catalysts
with low defect rate. Moreover, three types
of attachments allow you to produce:
powder, fiber and film.


Compact-sized equipment enables
the mass production of CNTs.
Caltema is compact enough to work even in
office buildings with small energies.
It enables you mass production of CNTs
at your service in your manufacturing site.




AI and IoT systems
make you free from complicated operations
Caltema is smart. Just enter what you need,
such as length, diameter and quantity.
AI optimizes conditions to meet your requirements.
Moreover, we offer you 24H remote monitoring
and maintenance through lot system.
