Advanced materials, engineered at 700 bar.
We deliver premium, high-performance materials developed with advanced high-pressure processing. Powered by our proprietary supercritical CO₂ facility operating at up to 700 bar, we engineer, refine and supply specialized materials, from graphene to aerogels, to the highest industry standards.
What Is Supercritical CO₂?
Carbon dioxide is usually a gas, the same CO₂ found in the air and in sparkling water. Once it is heated above 31.1 °C and compressed above 73.8 bar, it passes its critical point and becomes a supercritical fluid: neither a true gas nor a true liquid, but a state with the best of both.
Supercritical CO₂ is as dense as a liquid, so it can dissolve and carry substances like a solvent. At the same time it flows like a gas, with very low viscosity and no surface tension, so it reaches into the finest pores and structures.
When the pressure is released, CO₂ simply turns back into a gas and leaves the material. No drying step, no solvent left behind.
Gas, liquid or supercritical?
| Property | Gas | Supercritical CO₂ | Liquid |
|---|---|---|---|
| Density | Low | Liquid-like | High |
| Viscosity | Low | Gas-like | High |
| Diffusion | Fast | Fast | Slow |
| Surface tension | None | None | Yes |
| Dissolving power | Weak | Tunable | Strong |
The key advantage: small changes in pressure and temperature change the density, and with it the dissolving power. That makes supercritical CO₂ a solvent we can tune precisely for every material.
Why CO₂ is the ideal process medium
Why Supercritical CO₂
Our processing platform runs in a continuous, closed-loop CO₂ cycle, yielding exceptionally pure materials with zero organic solvent residues. By precisely tuning density, pressure and temperature, we achieve material properties, microstructures and purity levels that conventional methods cannot reach.
Exceptional purity
CO₂ leaves the product as a gas. What remains is a clean material with zero organic solvent residues.
Tunable properties
By adjusting pressure, temperature and density, we control particle size, porosity and microstructure.
Closed CO₂ loop
CO₂ is condensed, recycled and reused in every cycle, while a power loop recovers energy from the process.
How Our Process Works
One closed system, from CO₂ storage to finished material.
- 1
Pressurize
CO₂ from storage is compressed by a high-pressure pump.
- 2
Heat
Above 31 °C and 73.8 bar, CO₂ turns into a supercritical fluid.
- 3
React at 700 bar
Precursors are fed into the reactor and processed under precise conditions.
- 4
Precipitate
The material is separated in the precipitation vessel, ready to collect.
- 5
Recycle
CO₂ is chilled, condensed and returned to storage for the next cycle.
