“…Furthermore, low temperature sintering can provide advantages such as the reduction of energy consumption and PbO volatilization. Previously, Various manufacturing techniques such as hot pressing, liquid phase sintering, and use of ultra fine powders were applied to lower the sintering temperature of Pbbased ceramics while retaining good electrical properties [9][10][11][12]. Especially, it has been well known that liquid phase sintering is the most effective method for lowering sintering temperature of the ceramics [13,14].…”

“…Other works have confirmed that sintering temperature of PZT ceramics can be lowered by adding various sintering aids with different oxides and excess PbO, as mentioned by Sangawaret al [13]. However, others studies have shown that the sintering aids frequently worsen the electric properties [10][11][12][13]. Abreu et al [14] synthesized PZT52/48 ceramic by a chemical method.…”

“…The conventional sintering process of those ceramics uses powders prepared by solid state reaction (SSR) and requires high sintering temperatures (1200-1300°C). At this range of temperature PbO volatilization results in the degradation of electrical properties and causes environmental pollution [9,10]. In addition, the high sintering temperatures also limit the choice of electrodes for multilayer systems to noble metals as platinum or palladium.…”

“…In this context, others preparation methods have been employed to reduce temperature sintering of PZT ceramics since 1980's [11]. Under certain conditions, Mazumder and Sem [10] showed PZT Pb(Zr 0.52 Ti 0.48 )O 3 can be sintered at a temperature as low as 715 °C. They concluded that the dielectric and piezoelectric properties of the LiBiO 2 (LBO) added sintered samples were on a par and in some cases better than those of high-temperature conventionally sintered PZT without addition of LBO [12].…”

Lead zirconatetitanate solid solutions, Pb(Zr1-xTix)O3 – PZT, are widely recognized for representing a special group of ferroelectric materials with various potential applications in electroceramics and (micro)electronic devices. The PZT ceramics is produced by solid state reaction (conventional route) and temperatures frequently above 1200 °C. As a consequence, the cost of ceramic product is expensive. Herein, we present the synthesis and processing conditions of PZT52/48 (x = 0.48) ceramics in which it was possible to lower the sintering temperature down to around 900°C. We have applied a route for PZT52/48 obtaining ferroelectric ceramics through sintering of nanometric powders prepared by the polymeric precursor synthesis method (modified Pechini’s method). The sintering was achieved with a temperature of 900ºC for 2 hours and the samples got 96% of their theoretical density and 1.3 mm mean grain size. The electrical permittivity of the ceramic plates, studied by impedance spectroscopy, presented Curie temperature around 390 ºC. Ferroelectric hysteresis measurements revealed that the remnant polarization is 3.2 μC/cm2 and coercive field is 10 kV/cm at 60 Hz. All results and characterizations have shown that the PZT samples obtained with the polymeric route are efficient as the ones prepared in the conventional SSR protocol.

“…Piezoelectric-driven actuators can realize the power conversion and transmission and have applied successfully to the fields of ultrasonic cleaning [12,13], ultrasonic machining [14,15], and ultrasonic motors [16,17]. Since the piezoelectric ceramics show a wide temperature tolerance range, the ultrasonic drill actuated by piezoelectric ceramics has strong adaptive capacity in extreme environments [18].…”

The rocks on extraterrestrial objects contain plenty of original geological and biological information. Drilling and sampling are an essential task in lunar exploration or future explorations of other planets like mars. Due to the limitation of payloads, energies, and drill pressure, the investigation of a lightweight and low-powered rock-drilling device is crucial for explorations of distant celestial bodies. The ultrasonic drill driven by piezoelectric ceramics is a new drilling device that can adapt to the arduous space rock-drilling tasks in weak gravitational fields. An ultrasonic drill suitable for mounting on a planetary rover’s robotic arm is developed. The ultrasonic transducer’s energy conversion from electric energy to acoustic energy and the energy transmission from the horn’s high-frequency vibration to the drill stem’s low-frequency impact motion are analyzed to guide the design of the drill. To deeply understand the percussive drilling mechanism under high-speed impact, the interaction between the drill stem and the rock is simulated using LS-DYNA software. Drilling experiments on rocks with different hardness grades are conducted. The experiment results illustrate that the ultrasonic drill can penetrate into the hard rocks only taking a force of 6 N and a power consumption of 15 W. The study of ultrasonic drill will provide a reference method for sample collection of extraterrestrial rocks.
