What K3RX does

K3RX is an Italian deep-tech materials company that designs and manufactures ultra-high temperature ceramic matrix composite (UHTCMC) components for aerospace, defence, energy, and advanced industrial applications. Founded in 2021 as a spin-off of CNR-ISSMC (the National Research Council of Italy's Institute of Science and Technology for Ceramic Materials), the company commercializes patents and know-how from the Horizon 2020 C3HARME project. Its core offering consists of two proprietary material systems—UHTCMC Type Alfa (sintered, optimized for maximum density and erosion resistance) and UHTCMC Type Beta (pyrolyzed, optimized for complex geometries)—engineered for operating temperatures beyond 2000°C with oxidation resistance up to 2200°C in air and ablation resistance up to 2400°C. K3RX converts these materials into tailor-made components such as nosecones, thermal barrier tiles, leading edges, rocket nozzle inserts, and mechanical spacers for customers in atmospheric re-entry, hypersonic, and propulsion applications.

The business operates a direct B2B/B2G sales model, with no intermediaries or public pricing—engagement is initiated through a website inquiry form capturing industry sector, country, and technical specifications. Customers are aerospace and defence primes (primary segment), with adjacent verticals spanning energy (gas turbines, concentrated solar, fusion reactor components), braking systems, and industrial refractories. The company is in an industrialization phase, transitioning from R&D prototype output to scaled manufacturing supported by a €1.65 million funding round closed in February 2026 with Deep Ocean Capital SGR (Deep Blue Ventures) and RoboIT as lead investors. Geographic expansion from its Italian base into broader European and US markets is an explicit near-term priority.

K3RX is led by co-founder and CEO Giorgio Montanari and holds granted patents in both the US (US11180418B2, US20220002208A1) and Europe (EP3408245B1, EP3883906B1). It remains a private Italian S.r.l. headquartered in Faenza (Emilia-Romagna), with technology validated to TRL 5–6 in propulsion nozzles and thermal protection systems. At 1–10 employees, K3RX is a small, capital-efficient operation whose commercial trajectory will depend on converting validated TRL 5–6 technology into qualified production contracts with aerospace and defence customers.

Core offering

K3RX designs and manufactures tailor-made carbon-ceramic matrix composite (UHTCMC) components for extreme-environment applications. The company offers two proprietary material systems — UHTCMC Type Alfa (sintered for maximum density and erosion resistance) and UHTCMC Type Beta (pyrolyzed for complex geometries) — converted into aerospace components such as nosecones, tiles, leading edges, nozzles, and mechanical connectors serving aerospace, defense, energy, and advanced industrial sectors.

Product overview

K3RX is an Italian high-tech materials company and CNR spin-off that develops, designs, and manufactures ultra-high temperature ceramic matrix composites (UHTCMCs) for extreme-environment applications. The product portfolio consists of two material systems: UHTCMC Type Alfa (sintered for maximum density and extreme erosion/ablation resistance) and UHTCMC Type Beta (pyrolyzed for complex geometries). These materials are converted into specific aerospace and defense components including nosecones, tiles, leading edges, nozzles, and mechanical connectors. K3RX serves multiple markets including aerospace & defence, energy, braking systems, and industrial refractories, offering tailor-made carbon-ceramic matrix composite components engineered to meet demanding customer requirements for high-tech applications.
