LiNbO₃, prepared according to the traditional ceramic technology

Abstract

The paper is devoted to the development of the lithium metaniobate production method according to the traditional technology while keeping the high piezoelectric parameters. The introduction of modifying glass-additives is offered, possessing their own piezoelectric properties. Using of the glass-additive not more, than 2.5 wt.% in number allows to carry out the ceramic sintering in the temperature range of 1320–1360 K and to product the material with the mechanical strength of 25 MPa.
