Lithium aluminate and lithium silicate powders (Lithium Corporation of America) and Zero-X pellets (Ferro Corporation) have been analyzed spectrochemically, by x-ray diffraction, and for lithium, carbon, and water content. These data are presented along with some important physical constants of the materials. Aluminate and silicate powders are incompletely calcined, containing up to 3 wt percent residual lithium carbonate. They have lithium contents that are sub-stoichiometric by as much as 20 percent. They have moisture contents up to 7 wt percent. Aluminate powders contain a variable mixture of the ..cap alpha.. and ..gamma.. allotropes. Silicate powders have the single lithium meta silicate structure. Average particle size of the powders ranges from 75 to 100 microns. Zero-X pellets are calcined completely, and have stoichiometric lithium content, about 105 ppM water, and a density of 1.83 g/cc. Crystal structure is a solid solution of silica in ..beta..-Spodumene.
