In this paper, high-porosity Al 2 O 3 ceramic foams called Al 2 O 3 PHM ceramics were
fabricated through selective laser sintering (SLS) via Al 2 O 3 poly-hollow microspheres (Al 2 …

Ferroelectric ceramics are a technologically important class of materials that are currently
exploited in actuators, sensors, transducers, and memory devices. The introduction of …

The role of porosity on the low and high field dielectric properties was studied in Ba 0.70 Sr
0.30 TiO 3 ceramics with various porosity levels obtained by using lamellar graphite as …

In this study, we investigate the effective characteristics of a porous piezocomposite with
randomly distributed pores of arbitrary size and with partly metalized pore boundaries. Using …

Lead free piezoelectric K 0.5 Na 0.5 NbO 3 (KNN) is synthesised by the conventional solid
state mixed oxide route using dry ball milling. Spark plasma sintering technique (SPS) is an …

Membranes utilized for water and wastewater treatment are susceptible to fouling. Fouling
leads to gradual flux decline, possible loss of selectivity and increased operational costs …

Porous lead zirconate titanate (PZT) ceramics with interconnected pores were fabricated by
using a novel tert-butyl alcohol (TBA)-based gel-casting method. The resultant samples …

Micromechanical models of porous ferroelectric ceramics have often assumed that the
material is fully polarized in a particular direction and/or consists of a single isolated pore. In …

This paper is concerned with direct energy conversion of waste heat into electrical energy by
performing the Olsen cycle on lead nickel niobate zirconate titanate (PNNZT) pyroelectric …
