5 FAQs of Aluminum Oxide Spherical Alumina Powder White Fused Alumina Powder for Refractory

Here are five common questions about Aluminum Oxide Spherical Alumina Powder and White Fused Alumina Powder for refractory applications:

What is Aluminum Oxide Spherical Alumina Powder? This powder is made of pure aluminum oxide (Al2O3). Its particles are shaped like tiny, perfect spheres. This shape is key for high-performance refractory materials.

Why is the spherical shape important for refractories? Spherical particles flow better. They pack together much more tightly. This dense packing creates stronger refractory structures. It also reduces the amount of binder needed. This improves the refractory’s final performance.

What particle sizes are available? Suppliers offer many different particle sizes. You can get very fine powders. You can also get coarser powders. The size needed depends entirely on the specific refractory application. Common ranges are from a few microns up to several hundred microns.

How does spherical powder compare to angular White Fused Alumina? White Fused Alumina (WFA) is also aluminum oxide. Its particles have sharp, angular shapes. Spherical alumina flows much better. It packs denser. Angular WFA is cheaper. It is often used where maximum density isn’t the absolute top requirement. Spherical powder offers superior performance for critical applications.

What temperature can this powder handle? Both spherical alumina and white fused alumina powders are extremely heat resistant. They easily withstand temperatures exceeding 1800°C (3272°F). This makes them ideal for lining furnaces, kilns, and other extreme heat environments. Their high purity prevents contamination at these temperatures.
