1.V₂CTx MXene precursor:Mature HF etching route; mechanism studied (core–shell etching mechanism, J. Mater. Res. 2023), Ti-assisted exfoliation (Ceram. Int. 2017), low-cost combustion synthesis of the V₂AlC precursor (2023); microwave + HF intensified etching needs 80 °C/96 h to complete
2.Ag-based electrical contact materials:Ag–20 vol% V₂AlC (SPS): arc ablation at 7 kV, breakdown current23.8 A; the arc ablation mechanism evolves with increasing discharge cycles, and the V₂AlC phase still retains its original size and shape after a single ablation
3.Cu/graphite electrical contact materials:At high temperature V₂AlCdecomposes in situ to VC and releases V, forming a VC layer at the copper–graphite interface: interfacial nanoindentation hardness1.46 → 6.12 GPa; composite hardness19.6 → 76.3 HV0.2; compressive strength132 → 218 MPa
4.Supercapacitor electrode:27.6 F/gat 0.5 A/g,93.8%retention after 2000 cycles
5.MAX solid-solution precursor:Ti₂AlC–V₂AlC solid solutions synthesised by molten salt at 1000–1100 °C as heterometallic MXene precursors
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.
