Barium Ruthenate(IV), TU 6-09-05-1199-82

Barium ruthenate(IV) BaRuO3 is a mixed oxide of barium and ruthenium, not metallic ruthenium. The formal composition corresponds to Ba(II), Ru(IV), and oxide ions, but the crystal modification, oxygen stoichiometry, and impurity phases are determined by the batch.

Confirmed characteristics

• Formula: BaRuO3
• Grade: pure
• Mass fraction of Ru: not less than 34.5%
• Appearance: black powder
• Document: TU 6-09-05-1199-82

Catalog number — 5162731. Other values are to be confirmed by CoA.

Chemical and technological features

Synthesis conditions of BaRuO3 can lead to different polytypes. Therefore, the same elemental formula does not imply identical electrical, magnetic, or catalytic properties. The black color does not replace phase analysis.

Typical applications

• research on conducting and magnetic complex oxides after structure confirmation;
• production of ceramics and targets with controlled phase, density, and grain size;
• comparative catalytic and electrochemical testing after determining surface area;

Suitability is confirmed by testing in your own process.

What to agree on before ordering

Request a CoA with Ru, Ba, and impurity content, CAS, phase composition by XRD, oxygen stoichiometry, particle size distribution, specific surface area, and moisture. For ceramics, agree on temperature, atmosphere, and shrinkage; for electrodes, conductivity and compatibility with binder. Suitability is established by batch testing.

Safe handling

Toxicology of this phase cannot be extrapolated from metallic ruthenium or barium oxide. The solubility of barium compounds affects the risk, and acid may alter the form of the material; follow the SDS. Work under local exhaust, avoid dust generation, dry sweeping, and eye contact. This Ru(IV) oxide is not volatile RuO4. The formation of the strong oxidizer RuO4 should be assessed separately for operations with strong oxidizers or oxidative heating. Collect waste as barium- and ruthenium-containing.
