Abstract
Spherical particles of lithium aluminate are formed by initially producing aluminum hydroxide spheroids, and immersing the spheroids in a lithium ion-containing solution to infuse lithium ions into the spheroids. The lithium-infused spheroids are rinsed to remove excess lithium ion from the surface, and the rinsed spheroids are soaked for a period of time in a liquid medium to remove water and NH.sub.4 OH from their surfaces. The soaked spheroids are then dried and sintered to form lithium aluminate spherical particles.
