Specification of High Purity Fine Calcined Aluminium Oxide Alpha Alumina Powder Al2O3

This alumina powder is pure aluminium oxide. Its chemical formula is Al2O3. It is the alpha crystalline stage. This phase is stable and tough. The powder goes through high-temperature calcination. This heat therapy repel impurities. It also makes the crystals fully establish. The outcome is a very pure material. Common pureness exceeds 99.99%. This means very little impurities. Impurities like salt or silicon are extremely low. This high purity is important for requiring uses.

The bit size is great and regulated. We exactly grind and categorize the powder. This ensures constant bit circulation. Typical dimensions range below 1 micron to 10 microns. Some grades are also better. The powder feels smooth. It moves quickly. This flow helps during handling. The powder packs densely. This density enhances final product buildings.

Alpha alumina is really secure. It stands up to high temperatures well. Its melting point mores than 2000 ° C. This makes it excellent for warm. It is likewise very difficult. Only diamond and a couple of others are harder. This hardness provides excellent wear resistance. The product is chemically inert as well. It endures strong acids and bases. It does not dissolve easily. Electrical insulation is an additional key function. It functions even at high voltages and temperature levels.

These buildings make it essential in several industries. It reinforces advanced porcelains. Believe reducing devices and put on plates. It brightens surfaces specifically. Semiconductor manufacturing relies upon its pureness. It goes into grinding media and sandpaper. It serves as a filler in unique plastics. High-performance refractories use it. It helps catalysts function better. It is vital for high-tech abrasives. Its quality defines the final product performance.

5 FAQs of High Purity Fine Calcined Aluminium Oxide Alpha Alumina Powder Al2O3

What is alpha alumina powder?
It’s a very pure form of aluminum oxide. It’s made by heating other types of alumina very hot. This changes its structure. This structure is called the alpha phase. It’s the hardest and most stable kind.

Why is high purity important?
Impurities hurt performance. Even tiny amounts of other elements cause problems. They weaken the final product. They make it less resistant to heat and chemicals. High purity powder gives better results. It makes stronger ceramics and coatings.

What does particle size mean for use?
The size of the powder grains matters a lot. Smaller grains pack together more tightly. This makes denser, stronger ceramics after firing. Finer powders work better for polishing. They give a smoother finish. Bigger grains might be used for grinding or fillers. Choose the size for your job.

How heat resistant is this powder?
Alpha alumina powder handles extreme heat very well. It doesn’t melt until over 2000°C. It keeps its strength and shape at high temperatures. This makes it perfect for furnace parts, kiln furniture, and heat shields. It won’t break down easily.

Is it safe to handle?
Yes, but take care. The fine powder can irritate your lungs and skin. Always wear a dust mask. Wear gloves and safety glasses. Work in a well-ventilated area. Avoid breathing the dust in. Keep it away from your eyes and skin.
