Production Method of Spherical Aluminum Oxide Al2O3 Powder

1. Spray Pyrolysis
   Dissolve light weight aluminum nitrate (Al( NO ₃) ₃) in water. Atomize the remedy into fine droplets making use of a spray nozzle. Warmth the beads in a furnace at 800– 1200 ° C. The solvent evaporates, and the nitrate decomposes to develop Al ₂ O ₃ balls. The reaction is:
   2Al( NO ₃) ₃ → Al ₂ O ₃ + 6NO ₂ + 1.5 O ₂.
2. Sol-Gel Method
   Mix aluminum alkoxide (e.g., Al( OC ₃ H ₇) ₃) with ethanol. Add water to start hydrolysis. Mix till a gel forms. Dry the gel and warm it at 500– 800 ° C. The organic parts burn, leaving round Al ₂ O ₃ bits.
3. Vapor Phase Oxidation
   Heat light weight aluminum chloride (AlCl ₃) gas with oxygen at 1000– 1500 ° C. They react to form Al ₂ O ₃ powder:
   4AlCl ₃ + 3O ₂ → 2Al ₂ O ₃ + 6Cl ₂. Great and gather the spherical particles.
4. Hydrothermal Synthesis
   Combine aluminum hydroxide (Al( OH) ₃) with water in a secured container. Warmth to 200– 300 ° C under pressure. The hydroxide dissolves and reforms as round Al ₂ O ₃ crystals. Filter and dry the item.
5. Mechanical Sphere Milling
   Grind irregular Al ₂ O ₃ powder in a ball mill with zirconia grains. The rubbing and effect reshape the fragments right into spheres. Control milling time and rate to get the preferred size.
   Each method produces rounds with different dimensions and purity levels.

Storage Condition of Spherical Aluminum Oxide Al2O3 Powder

1. Sealed Containers

Store the powder in tightly closed plastic bags or metal drums. This stops moisture and dust from getting in, which could cause clumping or lower purity.

2. Dry Environment

Keep it in a dry place. Use desiccants (like silica gel) inside the container to keep humidity below 40%. Moisture can make the powder stick together or react with other materials.

3. Avoid High Heat

Store at room temperature (15–25°C). High temperatures (over 500°C) might change the powder’s structure or cause it to fuse.

4. Chemical Separation

Keep Al₂O₃ away from strong acids, bases, and reducing agents. These can react with the powder and change its properties.

5. Gentle Handling

Move containers carefully. Don’t drop or shake them hard to prevent particle breakage or dust formation.

6. Label Clearly

Write the name, purity level, and storage date on the container. This helps track usage and ensures older batches are used first.
