Aluminum Silicate[3]
Overview
Aluminum silicate is an inorganic compound composed of aluminum, silicon, and oxygen, occurring naturally in minerals like kaolinite or synthesized for industrial use. It is valued for its thermal resistance, chemical stability, and versatility in high-temperature applications. As a key raw material, it exists in multiple polymorphs (e.g., andalusite, kyanite), with properties tailored for ceramics, coatings, and refractory linings. Synthetic variants offer controlled particle sizes and purity levels, making them indispensable in advanced manufacturing.
Physical and Chemical Properties
Aluminum silicate exhibits high melting points (exceeding 1,500°C) and low thermal conductivity, ideal for insulating materials. Its insolubility in water and resistance to acids (except HF) ensure durability in corrosive environments. The compound’s layered structure contributes to its mechanical strength and lightweight properties. Particle size distribution (typically 1–50 µm) and surface area (5–30 m²/g) are critical for performance in applications like catalyst supports or paint thickeners.
Main Applications
In ceramics, aluminum silicate enhances structural integrity and thermal shock resistance in tiles and tableware. Refractory industries rely on it for furnace linings due to its ability to withstand extreme temperatures. It also serves as a filler in paints and plastics, improving texture and UV resistance. Specialty grades are used in catalysis (e.g., fluid catalytic cracking) and as adsorbents in water treatment.
Safety and Storage
While non-toxic, fine aluminum silicate powders require handling with NIOSH-approved dust masks to prevent respiratory irritation. Spills should be vacuumed to avoid airborne dispersion. Store in sealed containers away from moisture and acidic vapors. Bulk storage silos should include desiccants to maintain product integrity. Disposal follows local regulations for inert minerals.
B2B Procurement Guide
Industrial buyers should prioritize suppliers with ISO 9001 certification and batch-specific COAs (Certificates of Analysis). Key specifications include Al₂O₃ content (≥35% for refractory grades), SiO₂ ratio (45–60%), and loss on ignition (LOI <1%). For cost efficiency, consider regional sourcing in China (major producer) or bulk contracts with MOQs of 5+ metric tons. Sample testing for particle uniformity and thermal stability is recommended before large orders.
