“…Piezo ceramics are applied in the industry of electronic components such as chip capacitors, filters, sensors and actuators. The main electrical parameters (resonant frequency and their tolerance) are connected to ceramic device dimensions and electrode surface value and their arrangement [21][22][23][24]. That is the main reason why piezo devices are planar with thick film electrodes and why they are known as laser trimmed devices.…”

In this article the PIM (Powder Injection Moulding) technology is described in brief. After that the benefits and advantages were analyzed and summarized. Ceramic injection moulding (CIM) process was analyzed in more detail: CIM- alumina, CIM-zirconia and CIM ferrites as the most common technical ceramics in CIM ceramic parts production, medical applications and accessories in chemical laboratories, and cores in electronic inductive components. After that our results for CIM barium hexaferrite and piezo ceramics (barium titanate) are given. The main powder characteristics, the shrinkage and density and the main electrical characteristics of the sintered samples were compared for the isostatically pressed PM (powder metallurgy) and CIM formed samples. SEM fractographs of CIM and PM samples are given for CIM green parts, debinded (white) parts and sintered parts, and PM green parts and sintered parts. The results obtained were compared to literature data before they were applied in ceramic components production

“…However, piezoelectric properties of above compositions are still weak for application in high-power devices such as piezoelectric transformers, ultrasonic motors or actuators. Because these devices should be electrically driven with high mechanical vibration at near resonance frequency, high mechanical quality factor (Q m ) with high electromechanical coupling factor (k p ) are simultaneously required [13]. Moreover, in order to enhance the thermal stability of piezoelectric properties, the tetragonal-orthorhombic phase transition (To-t), which can cause the domain instability between the two ferroelectric phases, should be shifted to above 150 • C and below room temperature.…”

“…The powers were first mixed with solvent comprised of methyl ethyl ketone and anhydrous ethanol with a weight ratio of 7:3 and dispersant of corn oil for 4 h by ball milling. Then, polyvinyl butyral (PVB) using as the binder and dibutyl phthalate (DBP) using as the plasticizer were added to the mixed slurry, and then ball milled again for 8 h to obtain castable slurry (Lee et al 2009;Choi et al 2008;Yoo et al 2007). The green sheets were tape-casted by a doctor blade method with thickness of 60 μm and dried at room temperature.…”

Multilayer ceramic actuator composed of piezoelectrically active 0.90Pb(Zr0.48Ti0.52)O3–0.05Pb(Mn1/3Sb2/3)O3–0.05Pb(Zn1/3Nb2/3)O3 (PZT–PMS–PZN) layers and electrically conducting silver metal layers were fabricated. Low-temperature sinterable PZT–PMS–PZN ceramics were used as the piezoelectric layers, and silver paste was used as the conductive inner-electrode layers. PZT–PMS–PZN powder, adding 1% CuO as a sintering agent, was prepared by a conventional solid-state reaction process. The green sheet was fabricated by tape-casting method. Silver inner-electrode was printed on the green-tape sheets and the sheets were stacked, warm-pressed, and sintered at 900°C for 4 h after burning out the organic additions. The sintered multilayer ceramics actuator shows distinct layers with few defects in the interfaces. The thicknesses of the piezoelectric and conducting layers are about 40 and 6 μm, respectively. The multilayer PZT–PMS–PZN actuator, composed of 60 active piezoelectric layers, presents a longitudinal displacement of about 2.7 μm at an applied voltage of 80 V, approximately 0.1% of the total thickness of itself.
