What is Cu-Zn-V Complex Vanadate?
Cu-Zn-V Complex Vanadate
Cu-Zn-V Complex Vanadate is a Cu2-xZnxV2O7 material family for NTE systems. The reference high-NTE fine-particle phase is beta-Cu1.8Zn0.2V2O7; literature values remain phase- and process-specific.

Bukan apa
- The beta-Cu1.8Zn0.2V2O7 high-NTE reference phase is not interchangeable with the alpha-Cu2-xZnxV2O7 solid-solution route.
When Not to Use It
- Do not assign the published -14.4 ppm/K value without confirming beta-phase identity and retained microstructure after milling and integration.
- Do not use the literature measurement range as a continuous-service rating; 350 °C is a transient peak only for the supplied powder.
- Do not use the material in aqueous processing outside pH 7-10 without surface-stability validation.
Intrinsic Screening Summary
- Identity screen
- Cu2-xZnxV2O7 family; beta-Cu1.8Zn0.2V2O7 is the reference high-NTE phase; White inorganic vanadate ceramic powder
- Intrinsic feature
- The strong beta-phase contraction is microstructure-dependent. Ball milling can weaken the NTE response, and annealing can partly restore it, so phase and microstructure must be rechecked after processing.
- Material-level integration
- Confirm exact Cu/Zn ratio, alpha or beta phase fraction, particle-size distribution, milling history, annealing history, and post-process CTE. Do not transfer the beta-Cu1.8Zn0.2V2O7 research CTE to an unidentified Cu2-xZnxV2O7 grade.

Why It Works
| Struktur | Fungsi | Mekanisme |
|---|---|---|
| Cu2-xZnxV2O7 material family; published high-NTE fine-particle reference is beta-Cu1.8Zn0.2V2O7. | Non-zirconium NTE route for CTE control where vanadate chemistry and color are acceptable. | The strong beta-phase contraction is microstructure-dependent. Ball milling can weaken the NTE response, and annealing can partly restore it, so phase and microstructure must be rechecked after processing. |
Compare Material Routes
| Material / Route | Decision Boundary |
|---|---|
| Zirconium Tungstate | The beta-Cu1.8Zn0.2V2O7 reference phase offers a non-zirconium microstructure-driven NTE route with research CTE near -14 ppm/K. Phase and microstructure can be disturbed by milling, and vanadate chemistry, color, regulatory documentation, and matrix compatibility require separate qualification. |
