Why is the alpha crystal phase specified for this 0.2 µm aluminum oxide polishing powder?
The alpha phase (α-Al2O3) is the most stable and hardest form of alumina, making it ideal for precision polishing where consistent abrasion and minimal contamination are critical. This product is specified as alpha-phase, with 99.99% purity and a controlled 0.2 µm particle size, ensuring a high-quality, reproducible surface finish for research applications.
What specific precision polishing applications is this 0.2 µm alumina powder designed for?
This powder is intended for research involving precision polishing of materials such as metals, ceramics, and optics, where the 99.99% purity and 0.2 µm particle size enable controlled surface finishing without introducing contaminants. The defined alpha-phase crystal structure provides the hardness required for effective material removal in fine polishing steps.
What are the recommended storage conditions for this 99.99% purity aluminum oxide powder to maintain its properties?
Store in a dry, sealed container at room temperature to prevent moisture absorption and contamination, which can affect the 0.2 µm particle size distribution and high purity. The manufacturer provides a Certificate of Analysis (COA) and Safety Data Sheet (SDS) upon request for batch-specific quality confirmation and handling guidance.
Atomfair Aluminum Oxide Polishing Powder (99.99% purity, 0.2 µm alpha phase) is evaluated for precision polishing applications, with high purity minimizing contamination and controlled particle size enabling consistent surface finish.
Positive
- High purity grade 99.99%: The 99.99% purity reduces the risk of introducing foreign particulates or contaminants during precision polishing, which is critical for research-grade surface finishing.
- Defined alpha-phase and particle size: The alpha-phase crystal structure combined with a 0.2 µm nominal particle size provides predictable abrasive behavior and consistent material removal rates for fine polishing applications.
Trade-offs
- Dust control required for handling: As a white powder with sub-micron particles, airborne dust generation is likely during transfer, requiring proper ventilation, fume hood use, or protective equipment to minimize inhalation risk.
- COA and SDS not automatically included: Batch-specific Certificate of Analysis and Safety Data Sheet are provided only upon request, meaning end users must proactively request documentation for quality assurance and compliance.
