Meet Halloysite

Halloysite, an aluminum silicate clay, with naturally occurring nanotubular structure, is the ideal feedstock material from which to economically scale production of nano-silicon.

Our halloysite has the chemistry, shape, and nanoparticle size that others are attempting to produce synthetically:

Chemical formula:



Naturally occurring nanotube structure with silicon oxide shell that is ready to use, allowing us to work “top down”

Average length:

500 nanometers

Average diameter:

50 nanometers


25% pore volume

15 nanometers average pore size


Abundant; multi-million tons in reserve on our site that we’re capable of mining at rate of 30,000 metric tons per month

Mining Method:

Simple excavation from the earth’s surface using environmentally friendly methods without water or chemicals


Safe, non-toxic, natural earth mineral

Synthesized by Nature

Halloysite Nanotube morphology Close up of Halloysite

The biggest challenge of producing nano-silicon at scale is controlling its morphology. With our feedstock this challenge has been solved in the ground by nature over a period of 35 million years. This is our key competitive advantage.

Our Capabilities

View of one of our facilities
Ionic MT has a 7,500 square foot pilot plant and lab space, including:
  • Full battery testing lab
  • Wet beneficiation of halloysite
  • Pilot Scale Silicon Production Facility


Ionic MT also has a 36k sq foot large scale production plant in construction that will be complete at the end of Q2 2023. The plant will be capable of producing tens of thousands of metric tons of nano-silicon per year and will give us the room to grow exponentially.
