Carbonium Core

Carbonium Core is a U.S.-based advanced materials company specializing in the production of ultra-pure, nuclear-grade graphite for 4th-generation nuclear reactors, including Small Modular Reactors (SMRs) and High-Temperature Gas-Cooled Reactors (HTGRs). Headquartered in Tennessee, the firm utilizes a proprietary molten-salt purification technology... developed in partnership with Oak Ridge National Laboratory (ORNL) to transform domestic coal waste into high-value carbon products with over 99.9% purity. Carbonium Core operates a vertically integrated supply chain, from exclusive mine access in Tennessee to final shaping and finishing of graphite pellets, rods, and spheres. By avoiding toxic acid-based chemicals and prioritizing domestic sourcing, the company provides a sustainable and secure alternative to foreign graphite supplies, directly supporting U.S. energy independence and the global transition to clean, carbon-free nuclear energy.Read More
