BoehmiteAlOOH · aluminium oxide-hydroxide
A practical technical and sourcing hub for engineers, battery teams, formulators and procurement professionals evaluating boehmite for separator coatings, electrode-edge coatings, catalysts, ceramics, polymers and specialty abrasives.
Commonly written AlOOH. Crystalline aluminium oxide-hydroxide; distinct from pseudoboehmite and from the diaspore phase.
From “what is boehmite?” to a purchase specification
A single-word search often starts as technical research, but industrial users quickly move toward grade selection, supplier comparison, sample requests, SDS/TDS review and commercial quotation.
Why boehmite matters in lithium-ion batteries
Commercial battery-grade boehmite is used for ceramic separator coating and electrode-edge coating. Suppliers emphasize thermal stability, controlled particle size, low impurity levels, dispersibility and wettability.
Commercial grade families
“Boehmite” alone is not a sufficient purchase specification. Grade design is application-driven.
Battery-grade boehmite
For separator and electrode-edge coatings. Typical discussion points include narrow PSD, low Na/Fe, low magnetic contamination, morphology, dispersion behavior and surface treatment.
Catalyst / alumina precursor
Used as an alumina precursor or in catalyst-support systems. High surface area and pore properties may be more important than the requirements used for battery coatings.
Functional filler grades
Used where heat resistance, surface chemistry, filler morphology or conversion to alumina are desired. Supplier-specific technical validation is essential.
Key data procurement teams should request
| Parameter | Why it matters | Typical documentation |
|---|---|---|
| Phase / identity | Confirms boehmite rather than another aluminium hydroxide-oxide phase or pseudoboehmite-rich material. | XRD, CAS, TDS |
| Particle size distribution | Controls coating thickness, rheology, pore structure, surface quality and processing behavior. | D10 / D50 / D90, laser diffraction |
| Specific surface area | Influences adsorption, binder demand, dispersion and catalyst-related behavior. | BET m²/g |
| Trace impurities | Battery and electronic uses can be sensitive to Na, Fe, Cu, Ni, Zn and magnetic contaminants. | ICP, magnetic impurity data, COA |
| Moisture / LOI / pH | Important for storage, slurry formulation and consistency. | COA / TDS |
| SDS / regulatory status | Required for EHS review, shipping and internal supplier approval. | Supplier-specific SDS |
