What is spherical alumina?

The so-called alumina ball, as the name suggests, is a type of alumina with a spherical particle morphology. In terms of the type of crystal phase, it is α— Aluminum oxide.

Why should we highlight the "sphere"? This is because the application of alumina is too extensive, and the application performance of alumina products in many fields is closely related to the morphology and size of raw material powder particles. Among different shapes of powder particles, spherical particles have regular morphology, smaller specific surface area, larger stacking density, and better fluidity, which can greatly improve the application performance of products.
