Shockwave loading in various technological stages may significantly influen
ce the defect state of synthesized LiNbO3, LiTaO3, Sr2Nb2O7, and Ca2Nb2O7 p
owders. This factor, in addition to comminution of the materials, leads to
a sharp decrease in the temperature of synthesis and sintering, with a simu
ltaneous increase in the relative density and degree of crystal structure p
erfection of the final ceramics. These effects can markedly simplify the te
chnology of production of these ferroelectric materials. (C) 2000 MAIK "Nau
