“…Using Newnham's connectivity notation, 1‐3 describes a composite structure where piezoelectric ceramic rods or fibers are embedded in a passive polymer matrix and are aligned along the poling direction. All of the commercially available piezoelectric ceramic fibers or rods are based on lead zirconate titanate (PZT) compositions due to the superior electrical properties of these materials . However, in the last decade, use of lead‐containing materials even in electronic equipment are gradually being restricted through national laws or directives of international bodies due to the toxicity of lead .…”

Highly [001] textured KSr2Nb5O15 (KSN) ceramic fibers were fabricated by a combination of novel alginate gelation method and templated grain growth using acicular KSr2Nb5O15 template particles. The needle‐like KSN template particles were prepared by molten salt synthesis method with salt/powder ratio of 2 giving the highest aspect ratio. Fibers were extruded into CaCl2 salt solutions from alginate‐based slurries without or with 10 wt% KSN template particles using a nozzle with 2 mm diameter and 80 mm length. Varying sintering temperature from 1300°C to 1450°C and time from 2 to 6 h were found to increase the texture. A maximum degree of orientation, ƒ(00l), of 0.95 was obtained, as measured by Lotgering factor, and a grain orientation distribution, r, of 0.28 was obtained as measured by rocking curve analysis.

“…There are several manufacturing processes that can be employed for PZT/polymer composites, including dice‐and‐fill 10 and injection‐molding 11 . In these processes, the PZT phase is formed first, and it is then embedded in a polymer matrix.…”

A piezoelectric ceramic/polymer composite with 2‐2 connectivity was fabricated by thermoplastic green machining. A thermoplastic body, consisting of 60 vol% lead zirconate titanate ceramic particles (PZT) and 40 vol% thermoplastic binders, was computer numeric controlled‐machined, creating periodic channels in the green PZT body. Following thermal treatment (binder burnout and sintering), a 25 vol% array of 147 μm thin PZT slabs with an aspect ratio of seven separated by 442 μm channels was fabricated. The channels were infiltrated with epoxy resin, in order to fabricate the PZT/epoxy composite with 2‐2 connectivity. This novel process was evaluated in terms of the machinability and sinterability of the thermoplastic PZT compound. Also, the electromechanical properties of the PZT/epoxy composite were measured.

“…Several structuring techniques have been recently applied to ceramic microstructures with simple configurations [1], [2]. For more desired ceramic microstructures with complex shapes or a high aspect ratio, injection molding is widely utilized [3]- [5]. However, a normal ceramic injection-molding process [6], [7] has difficulty keeping the green body of the microstructure free from fracturing when demolded.…”

A fabrication process for complex ceramic microstructures was proposed that combines a lost mold technique and ceramic injection molding. Two key points in this process were studied. First, the solubility of several engineering plastics in various organic solvents was tested to find appropriate combinations of mold material and solvent for dissolving molds. Secondly, the binder extraction rate and the strength of a green body during debinding were investigated. Experimental results indicate that acrylonitrile-butadiene styrene and acetone are the best combinations selected for this lost mold technique. We also propose that using gasoline as the debinding solvent and performing the debinding at room temperature will give a good time-saving effect and avoid toppling the microstructure if paraffin wax, stearic acid, and polyethylene were selected to compound the binder system. This process has been successfully applied to fabricate several ceramic microstructures, such as integrated punch. [575]
