摘要：

Lithium titanium phosphates mixed with various metal ions of M3+ (M=Al, Cr, Ga, Fe, Sc, In, Lu, Y, or La), Li1+xMxTi2-x(PO4)3 systems, were prepared, and their properties were investigated. The conductiv ity was enhanced and the porosity of the sintered pellets decreased by the partial replacement of Ti4+ with the M3+ ion. The porosity was considerably influenced by the ionic radius of the M3+ ion. The sinterability was greatly related to the increase of lithium concentrations at the grain boundary. The conductivity enhancement by the substitution mainly resulted from the densification of the sintered pellets. © 1990.
