5 FAQs of White Fused Alumina Powder Aluminum Oxide Ceramic Refractory Materials

What is white fused alumina powder?
White fused alumina powder is a man-made material. It comes from melting pure alumina raw materials. The process happens at very high temperatures. The result is a white powder. This powder has high purity. It contains aluminum oxide. The purity level is usually above 99%. It is a key material for making strong ceramics and heat-resistant products.

Why use white fused alumina powder?
This powder is very hard. It is almost as hard as diamonds. This hardness makes things last longer. Products resist wearing down easily. It also handles heat extremely well. It doesn’t break down at high temperatures. This is vital for furnaces and kilns. It is strong against chemicals too. Acids and alkalis don’t damage it easily. These properties make it reliable.

What are its main features?
The powder has several key features. Its high melting point is important. It works well over 2000°C. Its thermal shock resistance is good. This means it can handle sudden temperature changes without cracking. Its strength is impressive. It keeps its shape under pressure. Its chemical stability is excellent. It doesn’t react with most substances. These features make it versatile for tough jobs.

Does particle size matter?
Yes, particle size is very important. Different jobs need different sizes. Coarse grains give strength. They are good for heavy grinding. Fine grains give a smooth finish. They work well for polishing. Medium grains are often used for bonding. The size controls how the powder packs together. This affects the final product’s density and strength. Choosing the right size is crucial for performance.

Is it safe to handle?
