Material Identity
- Chemical name: Strontium vanadate
- Formula: SrVO3
- CAS number: not consistently defined in public databases for this phase
- Physical form: inorganic oxide, typically handled as a ceramic powder
- What it is not: not a carbon conductor, not a polymer additive, not a metallic filler
Activation & Trigger Conditions
- Trigger: lattice-level electronic structure associated with perovskite oxide framework
- Energy domain: electronic band transport governed by crystal structure and defect chemistry
- Absent trigger: poor crystallinity or incorrect phase suppresses expected behavior
- Insufficient condition: low-temperature or poorly controlled processing yields inconsistent response
- Excess condition: overly aggressive thermal treatment can induce secondary phases or stoichiometry drift
Functional Role
- Reference material for studying electronic transport in perovskite oxides
- Model system for structure–property relationships in functional ceramics
- Benchmark oxide for comparing processing and phase-control effects
Application Windows
- Compatible systems: oxide ceramics, electronic materials research platforms
- Loading range: system-dependent; no universal loading applies
- Processing notes: properties depend on calcination, atmosphere control, and sintering history
Limitations & Failure Modes
- Phase instability → altered crystal structure → loss or change of expected electronic behavior
- Impurity incorporation → defect chemistry modification → batch-to-batch variability
- Inadequate densification → microstructural discontinuities → inconsistent measurements
Alternatives & Trade-offs
- Carbon-based conductors: rely on percolation networks rather than lattice transport
- Doped metal oxides: offer tunability but introduce additional compositional variables
- Metal powders: provide high conductivity but lack ceramic stability and oxide compatibility
When to Use
- When investigating perovskite oxide electronic behavior under controlled processing
- When a ceramic-compatible conductive oxide is required for research comparison
- When studying structure–property coupling rather than bulk conductivity alone
FAQ
Is SrVO3 a universal conductive additive?
No. Its behavior is tied to crystal structure and processing, not simple filler loading.
Does it behave like carbon black or graphene?
No. Charge transport mechanisms differ fundamentally from carbon-based percolation systems.
Why do reported properties vary across studies?
Differences in phase purity, stoichiometry, atmosphere, and thermal history strongly affect outcomes.
Data
No generalized numerical values are provided. Users should rely on measured COA, phase analysis, and system-specific testing.
