How does the 0.3-10um particle size distribution and 99.999% purity of this alpha alumina powder affect its performance in sapphire crystal growth?
The controlled particle size range (0.3-10um) ensures consistent packing density and sintering behavior, critical for producing uniform sapphire crystals. The 99.999% purity minimizes trace element contamination that could lead to crystal defects, coloration, or reduced optical transmission. The specific surface area of 5-15 m2/g provides sufficient reactivity for solid-state reactions during sintering.
Why is the alpha-phase specification important for this high-purity aluminum oxide powder?
The alpha-phase (corundum) is the thermodynamically stable crystalline form of Al2O3 at high temperatures and is essential for sapphire crystal growth. It provides the required crystal structure lattice parameters and thermal stability for single-crystal sapphire fabrication. The 99.999% purity further ensures that the phase purity is maintained without secondary phases.
What documentation is available for safe handling and quality assurance of this high-purity alumina powder?
COA (Certificate of Analysis) and SDS (Safety Data Sheet) are available upon request for batch-specific confirmation. The product is a white, fine powder (Al2O3, CAS 1344-28-1) and should be handled with standard laboratory precautions for fine particulates, including avoidance of dust inhalation and storage in a dry environment.
Atomfair High-Purity Alpha Aluminum Oxide Powder (99.999%, 0.3-10 um, alpha phase) is evaluated for sapphire-crystal research applications. Its defined crystallinity and high purity support advanced studies, but the broad particle size distribution and research-grade designation require careful consideration for production-scale use.
Positive
- Ultra-high 99.999% purity: The 99.999% purity grade minimizes contamination risks in sensitive sapphire-crystal research, where trace impurities can disrupt lattice formation and optical properties.
- Defined alpha phase and particle size: The alpha-phase crystal structure and controlled 0.3-10 um particle size range with 5-15 m2/g specific surface area provide reproducible starting material for crystallization studies and substrate preparation.
Trade-offs
- Broad particle size distribution: The 0.3-10 um size range may require additional sieving or classification for applications demanding a narrow particle size cutoff, such as slurry formulation or uniform seeding.
- Research-grade scope only: This powder is explicitly intended for research and development use; it is not validated for production-scale sapphire crystal growth without further qualification and process optimization.
