Promethean Particles (PROM) is a UK-based SME that designs and develops inorganic nanomaterials in liquid dispersions. The company technology is based on a patented reactor system that allows truly continuous hydrothermal synthesis of inorganic nanoparticles for the first time. Promethean uses continuous hydrothermal (or solvothermal) synthesis to make the optimum product for each application and backs this up with pilot-scale production facilities, as well as a brand new multi-ton scale nanoparticle manufacturing plant (capacity more than 1000 tons per year). Our unique production process allows us to tailor the nanoparticles to get the best functionality for an end use application.

Our capabilities include, but are not limited to, metals (e.g. Ag, Cu, Au), metal oxides (e.g. SiO2, ZrO2, CeO2, Fe2O3, Fe3O4 etc.), ceramics (e.g. BaTiO3), and more complex materials such as metal organic frameworks (MOFs) - materials which could be used for catalysis, electronics and thermal applications, as examples. The versatility of our manufacturing technology, coupled with our scale of production, means our products are applicable to a vast range of market areas.
