Bismuth(IV) ruthenate, TU 6-09-05-1181-84

Bismuth(IV) ruthenate Bi2Ru2O7 is a mixed oxide where Bi(III) and Ru(IV) give a neutral composition. In the literature it is considered a pyrochlore-type ruthenate, but the name and black color do not confirm single-phase nature, crystallite size, or oxygen index.

Confirmed characteristics

• Formula: Bi2Ru2O7
• Grade: pure
• Mass fraction of Ru: not specified
• Appearance: black powder
• Document: TU 6-09-05-1181-84

Catalog number — 5162733. Other values to be confirmed by CoA.

Chemical and technological features

The properties of Bi2Ru2O7 are related to the Ru–O network structure, oxygen defects, and surface state. Activity also depends on dispersion and heat treatment. The Ru norm is restored according to TU or CoA.

Typical applications

• research on conductive pyrochlore oxides and their structural-electrical properties;
• development of electrode compositions and testing of reactions involving oxygen;
• production of ceramics, coatings, and model catalysts after phase and surface control;

Suitability is confirmed by testing in your own process.

What to agree before ordering

Agree on CAS per SDS, mass fractions of Bi and Ru, impurities, phase composition by XRD, oxygen stoichiometry, particle size, specific surface area, and moisture. For electrochemistry, specify electrolyte, potential, loading, and stability; for firing, atmosphere and allowable ruthenium loss. The result is confirmed on the batch.

Safe handling

Treat the powder as a professional material with incomplete toxicological data for the specific phase. Use local exhaust, eye protection, and gloves per SDS; do not create aerosol and do not clean surfaces with compressed air. Bi2Ru2O7 with Ru(IV) is not volatile RuO4. For strong oxidizers, acids, or oxidative heating, assess in advance the formation of volatile ruthenium species and provide capture. Collect waste as bismuth- and ruthenium-containing.
