Abstract

Shockwave loading in various technological stages may significantly influence the defect state of synthesized LiNbO3, LiTaO3, Sr2Nb2O7, and Ca2Nb2O7 powders. This factor, in addition to comminution of the materials, leads to a sharp decrease in the temperature of synthesis and sintering, with a simultaneous increase in the relative density and degree of crystal structure perfection of the final ceramics. These effects can markedly simplify the technology of production of these ferroelectric materials.
