| Abstract: | Complex perovskite-type compounds with the general formula Pb(B+1/4B5+3/4)O3, where B+= Li+ and B5+= Nb5+ or Ta5+, were synthesized using a high-pressure technique and studied by X-ray powder diffraction. The X-ray patterns were indexed on the basis of a cubic cell with a 0= 4.071 Å for Pb(Li1/4 Nb3/4)O3 and a 0= 4.052 Å for Pb(Li1/4Ta3/4)O3. Electrical properties of the new perovskites were also studied. |
