Specification of Calcined Nano AL2O3 Powder High Purity 995max Alumina Powder for Polishing 1344-28-1

Calcined Nano AL2O3 Powder is high purity alumina. Its purity reaches 99.5% or higher. This powder is special because it went through a calcination process. Calcination heats the material very hot. This step removes water and other impurities. It also changes the crystal structure. The result is a very hard, stable powder.

The particles are extremely small. We call this nano size. Particle sizes are typically 50 nanometers or less. Such tiny particles are crucial. They allow for very fine polishing. You get smooth surfaces without deep scratches.

This alumina powder is ideal for precision polishing. It works well on hard materials. Polishing sapphire optics needs this powder. Polishing semiconductor wafers uses it too. Polishing precision ceramic components benefits from it. The nano particles create a uniform abrasive effect. This achieves excellent surface finishes.

High purity is key. 99.5% pure alumina minimizes contamination risks. Impurities could damage sensitive surfaces. This powder is reliable for demanding applications. Its chemical formula is Al2O3. The CAS Registry Number is 1344-28-1. This identifies the material precisely.

The calcined structure gives advantages. It offers high hardness. It provides excellent thermal stability. It ensures good chemical resistance. These properties make it long-lasting during polishing. The powder stays effective.

You can use this powder with different carriers. Water-based systems work. Oil-based systems work too. It integrates well into polishing slurries. The performance stays consistent. It meets strict industrial requirements.

Applications of Calcined Nano AL2O3 Powder High Purity 995max Alumina Powder for Polishing 1344-28-1

Calcined nano Al2O3 powder is high purity alumina. Its purity level reaches 99.5% maximum. People call it CAS 1344-28-1 too. This powder has extremely small particles. These nanoparticles are very hard. They are also very stable chemically. This combination makes the powder perfect for precision polishing jobs. It gives excellent results on many surfaces.

You need a reliable polishing agent for semiconductor wafers. This nano alumina powder is a top choice. It works great in Chemical Mechanical Planarization (CMP) slurries. The tiny particles create super smooth, flat surfaces on silicon wafers. This step is vital for making advanced computer chips. Consistent particle size matters a lot here. This powder delivers that consistency.

Optical components need flawless finishes. Lenses, prisms, and laser optics use this alumina powder. It polishes glass and crystals without scratching. The result is crystal clear surfaces with minimal light scattering. This is essential for high performance cameras, telescopes, and laser systems.

Polishing LED sapphire substrates is another key use. Sapphire is very hard. This alumina powder effectively smooths the surface. A perfect sapphire surface is necessary for bright, efficient LED lights. Metal parts benefit too. It polishes hard metals and alloys to a high shine. Think precision tools, bearings, or medical implants. The powder removes material evenly. It leaves a smooth, reflective finish.

Advanced ceramics also use this powder. Items like ceramic bearings, cutting tools, and electronic substrates need fine polishing. The nano alumina particles refine the surface. This improves the ceramic’s performance and lifespan. Its hardness controls material removal rates well. You get predictable polishing without damaging the piece. The powder is chemically stable. It doesn’t react badly with other slurry ingredients. This stability ensures consistent polishing results every time.
