Lead(IV) ruthenate, TU 6-09-05-1305-84

Lead(IV) ruthenate is a lead-ruthenium complex oxide. The nominal formula Pb2Ru2O6 reduces to the ratio PbRuO3 and is consistent with Pb(II) and Ru(IV). It should not be taken as a description of a single phase: an oxygen-deficient pyrochlore Pb2Ru2O6.5 is also reported in the literature.

Confirmed characteristics

• Formula: Pb2Ru2O6
• Grade: pure
• Mass fraction of Ru: not specified
• Appearance: black powder
• Document: TU 6-09-05-1305-84

Item number — 5162732. Other values are to be confirmed against the CoA.

Chemical and processing features

Oxygen stoichiometry and impurity phases affect conductivity and interaction with the binder. Therefore, the material is confirmed by XRD and a process trial.

Typical applications

• research on conductive phases for thick-film and composite resistive materials;
• production of lead-ruthenium ceramics with controlled oxygen stoichiometry;
• comparison of electrophysical properties of complex oxides after confirming the batch composition;

Suitability is confirmed by testing in your own process.

What to agree before ordering

Request the CoA and TU with the correct Ru specification, CAS from the SDS, Pb and impurity content, phase composition, oxygen index, particle size distribution, and specific surface area. For pastes, check compatibility with glass frit and binder, firing profile, resistance, and temperature coefficient. Loading is calculated after confirming stoichiometry.

Safe handling

The material contains lead: avoid inhalation and ingestion of dust, transfer of contamination, and eating in the work area. Use local exhaust ventilation, wet cleaning, or a HEPA vacuum; do not dry sweep or use compressed air. PPE and exposure monitoring are determined by the lead work plan and SDS. Ru(IV) ruthenate is not a volatile strong oxidizer like RuO4; the possibility of RuO4 formation is assessed separately for strong oxidizers and oxidative heating. Waste is managed as lead- and ruthenium-containing.
