Description

Strontium Lanthanum Aluminate is a high-purity, single-phase inorganic compound widely recognized for its advanced functional properties. This material is critical for applications requiring precise luminescent, catalytic, or dielectric performance. It is primarily utilized by manufacturers and R&D departments in the electronics, optoelectronics, and advanced ceramics industries.

Application

• Persistent Luminescent Phosphors (LPL): A key host material for long-lasting afterglow pigments used in safety signage, watch dials, and emergency pathway markings.
• Advanced Ceramics & Solid Electrolytes: Used in the formulation of high-performance ceramics and as a component in solid oxide fuel cells (SOFCs) due to its ionic conductivity.
• Catalyst & Catalyst Support: Serves as a support material or active component in catalysts for chemical synthesis and exhaust gas treatment.
• Optoelectronic Devices: Employed in the research and development of LEDs, displays, and other photonic components.
• Thermal Barrier Coatings (TBCs): A potential material for coatings that protect components in high-temperature environments, such as turbine engines.
• Research & Development: Used as a precursor or standard in material science research for developing new functional oxides.

Quality Control

Our Strontium Lanthanum Aluminate is manufactured under controlled conditions to ensure batch-to-batch consistency and high purity. Quality is verified through a suite of analytical techniques including X-ray diffraction (XRD) for phase purity and inductively coupled plasma (ICP) for elemental assay. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed in a dry environment to prevent absorption of moisture and CO₂.
