Beschreibung
Zusammenfassung:	The invention provides a preparation method of a lithium-based ceramic microsphere, which is mainly used for preparing a tritium breeder in a fusion reactor blanket. The preparation method comprises the following steps: mixing a binder, water and ceramic powder to obtain uniform slurry by ball milling; adding a defoamer, heating in water bath and then forming sol; dripping into a medium mutually exclusive with water by a dispersing device; after the slurry is dispersed in the medium, forming micro-spherical gel; and washing, drying and sintering the microsphere so as to obtain the lithium-based ceramic microsphere. The preparation method of the invention has simple raw material, convenient forming and low cost, and the prepared ceramic microsphere has good sphericity and internal pore structure.
