What is Lanthanum Titanate?
Lanthanum Titanate
Lanthanum Titanate is a phase-sensitive lanthanum–titanium oxide material family. La2Ti2O7 is the commercially relevant route for lead-free high-temperature dielectric and ferroelectric ceramic screening; LaTiO3 remains a separate correlated-oxide research route.

What It Is Not
- Lanthanum Titanate is not one unambiguous formula; LaTiO3 and La2Ti2O7 are distinct phases that require explicit confirmation.
When Not to Use It
- Do not use generic Lanthanum Titanate when the required phase is not confirmed as LaTiO3, La2Ti2O7, or another explicit stoichiometry.
Intrinsic Screening Summary
- Identity screen
- Lanthanum–titanium oxide; exact phase and stoichiometry require grade confirmation; Ceramic oxide powder; approved morphology required
- Intrinsic feature
- Ti valence and oxygen stoichiometry distinguish this route from the Ti4+-rich layered La2Ti2O7 route; phase identity must be established before electrical interpretation.
- Material-level integration
- Confirm composition, phase, particle-size distribution, agglomeration state, purity, morphology, density, and sintering behavior before formulation or component qualification. Final ceramic composition, forming route, firing profile, atmosphere, electrodes, and component geometry.

| Property | Value | Method |
|---|---|---|
| Composition | Lanthanum–titanium oxide; exact phase and stoichiometry require grade confirmation | |
| CAS / identity | Identity confirmation required | |
| Particle size | Grade-specific confirmation required | |
| Morphology | Ceramic oxide powder; approved morphology required | |
| Purity | Grade-specific confirmation required | |
| Storage | Keep dry and sealed; confirm grade-specific handling requirements before use | |
| Material-family identity boundary | LaTiO3 and La2Ti2O7 are distinct phase routes and must not share an unqualified formula, CAS number, or performance claim. | Confirm exact composition, oxygen content, and crystal phase using the grade-specific COA plus appropriate analytical methods. |
Why It Works
| Structure | Function | Mechanism |
|---|---|---|
| LaTiO3 oxygen-deficient perovskite route | Correlated-electron oxide research route | Ti valence and oxygen stoichiometry distinguish this route from the Ti4+-rich layered La2Ti2O7 route; phase identity must be established before electrical interpretation. |
| La2Ti2O7 layered perovskite-like route | Ferroelectric and dielectric ceramic research route | Layered crystal structure, phase purity, texture, porosity, and sintering history govern the measured dielectric and ferroelectric response. |
