摘要：

A manufacturing technology of porous ferroelectric ceramics on the base of pure and modified lead titanate and lead metaniobate compositions were developed. Special attention was given to the microstructure studying of porous ceramics with different porosity types. The porosity dependencies of elastic, dielectric and piezoelectric properties of the specified compositions were measured in 0-40% relative porosity range. It was shown that, the porous ceramics technology allows to produce stable in time piezoelements of such "technologically difficult" ceramics as lead titanate and lead metaniobate with excellent and reproducible properties.
