Description

Lithium Aluminum Silicate is a synthetic, high-purity inorganic compound valued for its unique combination of thermal stability, chemical inertness, and low thermal expansion. This engineered material is critical for applications requiring durable, heat-resistant components and stable substrates. It is primarily utilized by manufacturers in the ceramics, glass, electronics, and advanced materials industries.

Application

• Ceramics & Refractories: As a key component in high-temperature kiln furniture, crucibles, and insulating materials due to its excellent thermal shock resistance.
• Glass & Glass-Ceramics: As a nucleating agent and filler to control crystallization, improve mechanical strength, and reduce the coefficient of thermal expansion in specialty glass formulations.
• Electronics & Substrates: Used in ceramic substrates for thick-film and thin-film circuits, and as a dielectric material in capacitors, where dimensional stability is paramount.
• Catalyst Supports: Serving as a stable, high-surface-area support material for various industrial catalysts in chemical processing.
• Coatings & Composites: As a functional filler in high-performance paints, coatings, and polymer composites to enhance thermal properties and wear resistance.
• Dental & Biomedical Ceramics: In the formulation of specialized dental porcelains and bioceramics for its biocompatibility and strength.

Quality Control

Our Lithium Aluminum Silicate is manufactured under a strict quality management system. Each batch is analyzed to ensure consistent chemical composition, particle size distribution, and phase purity critical for performance in advanced applications. Certificates of Analysis (COA) detailing key parameters are provided with every shipment to guarantee traceability and compliance with your specifications.

Storage

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