The physical phases, crystal cell parameters and crystal grain sizes of series ceramic samples (Ba0.2Sr0.8)1-1.15yGdyTi1-0.5xZnxO3 (x=0.03864, y=0, 0.04,0.05, 0.06) prepared by solid phase reaction are measured by X-ray diffraction method. The results was following: (1) for the Gd3+ contenty _〈 0.04, the crystal structure of the (Ba0.2Sr0.8)1-1.15yGdyTi1-0.5xZnxO3samples belongs to the cubic crystal system of space group P432 (207) , P23 (195) , and the cell volume decreases slightly (-0.6%) with y; (2) for y= 0.05, 0.06, the crystal structure turns to the tetragonal system of space group P4/n ( 85 ), P41 ( 76), but the cell volume decreases a little ( - 2.7%) ; (3) To each sample is a ceramic of crystal ~rain sizes being 441-1222А and single crystal structure.
