Seeking Experimental Methods for Single Crystal Growth of Cu₃Co₂SbO₆ via Flux or CVT Technique

[zhongyuanLiu]

I am currently seeking reliable protocols for growing single crystals of Cu₃Co₂SbO₆, particularly via flux method or chemical vapor transport (CVT) technique. Any insights into the experimental conditions, solvent selection, or optimization strategies would be highly appreciated.
Key Information & Questions:
Flux Method:
Which fluxes are commonly used for transition metal antimonates (e.g., Sb₂O₃, alkali halides, or other solvents)?
What are the typical temperature ranges, holding times, and cooling rates?
Have you encountered challenges in suppressing secondary phases (e.g., Cu/Co oxides) during growth?
CVT Technique:
Recommended transport agents (e.g., I₂, Cl₂, or halide gases) and their optimal concentrations?
Temperature gradient setup (e.g., source temperature, growth zone temperature, gradient rate)?
Typical growth duration and vacuum/atmosphere conditions?
Characterization Reference:
If available, could you share literature references (e.g., DOI or title) reporting single crystal growth of similar compounds (e.g., transition metal oxides with Kagome/frustrated lattices)?

Additional consideration should be given to the addition of Na₂O or adjustment of B₂O₃ to prevent secondary Cu/Co oxide formation. Flux solvent composition should be adjusted to limit unwanted oxide phases.

Very interested in this topic,Monkey Mart I am also curious to see which flux or CVT conditions you would choose to limit side phases and achieve high-quality Cu₃Co₂SbO₆ crystals!
