1. High-temperature oxidation/corrosion-resistant coatings: Systematic oxidation studies of coatings in 900–1100 °C and 1230–1410 °C ranges; protection by in-situ α-Al₂O₃.
2.Self-healing ceramics / long-life seals:Pre-oxidation raises healing efficiency; Al₂O₃ fills notches
3.Conductive ceramic parts (EDM, electrodes, heating elements):Metallic conduction plus machinability
4.Composites / joining with metals: Cr₂AlC with Sn, Cu, Co, Fe, Ag (20 wt% each), HIP at 1000 °C/4 h/150 MPa: metals do not dissolve into the MAX phase but act as oxidising agents, draining Al to form intermetallics; after 10 h oxidation the kinetics are no better than pure Cr₂AlC; Cr₂AlC–Sn shows embedded Sn spheres / hollow shells
5.Cr₂CTx MXene precursor:Etching yields Cr₂CTx for HER, antimicrobial work, etc.; the commercial page notes it is "harder to etch than Ti₃Al₂C and needs tailored conditions"
Quality is engineered into every batch, not inspected in at the end — SAT NANO enforces rigorous testing and process control from raw material to finished powder, ensuring reliable, high-quality products every time.
