	Lead zirconate titanate - Wikipedia, the free encyclopedia
		In hard PZT, domain wall motion is pinned by the impurities thereby lowering the losses in the material, but at the expense of a reduced piezoelectric constant.
		PZT is used to make ultrasound transducers and other sensors and actuators, as well as high-value ceramic capacitors and FRAM chips.
		PZT is also used in the manufacture of Ceramic resonators for reference timing in electronic circuitry.

	SIS Mirror PZT Replacement
		PZT #2 was found by this method to be unresponsive.
		The PZT screw had been lock-tighted to prevent loosening because of the vibrations of the PZT and the screw was a Phillips head screw, so the head became rapidly stripped.
		The PZT come with a BNC connector attached, but originally, these had been cut off and the co-axial cable (an extra length was put in to account for the motion of the mirror slide) was spliced together.

	PZT 95/5 Material Development for Neuron Generator Applications Research Brief
		Since this PZT formulation is unique to neutron generators, there are no current U. suppliers.
		Several production-size 10 kg PZT powder batches have been prepared.
		Through application of chemical preparation techniques, we have developed a new route to this important material and demonstrated its robustness with regard to passing application-critical explosive functional testing.

	Rutgers scientists perform 'materials magic' to simplify crystal-making for electronics
		Riman and his colleagues conducted their research with lead zirconate titanate, or PZT, which is used in motion sensors, electrical capacitors and even for vibration damping in high-performance skis and tennis racquets.
		PZT has proven almost impossible to fabricate as a single crystal, which limits practical applications to the material's polycrystalline form; that is, a solid mixture of small crystalline particles.
		The Rutgers-led team created PZT particles using chemical processes, forming cubes of uniform shape and size, between two and three microns on a side (almost 50 times smaller than a grain of table salt).

	Piezoelectric PZT thick films: preparation and devices
		The PZT elements are thereby transferred to the target substrate.
		The PZT tape can be easily surface mounted to a curved structure or embedded in a structure which needs to be flexible, hence it can be widely used in many smart systems.
		The PZT elements in the tape can also work as sensors, actuators and transducers, thus itself is a smart panel or a smart skin.

	Characterization of Nanocrystalline PZT Synthesized via a Hydrothermal Method
		A sound knowledge of the underlying physical and chemical processes involved in the formation and applications of these particles is clearly essential for the successful development of devices.
		The PZT phase appeared after just 30 minutes of processing time at 140¡ãC. However, 2 hours of processing time at 160¡ãC was necessary to attain complete phase purity.
		Scanning electron microscopy was used to characterise the morphology of the PZT samples.

	FABRICATION OF HIGH QUALITY PZT THICK FILM USING LIFT-OFF TECHNIQUE
		The demand for the thickness of PZT films used in MEMS is usually over 1μm due to the advantages of the thick thin films, so the integration processes of silicon-based PZT films are the points.
		The PZT films obtained using single spin-coating with the thickness of 100μm or higher, which is proportional to the thickness of the photoresist SU-8, are crack-free and have good morphology.
		The PZT films with perfect perovskite structure have excellent piezoelectric property and the d33 is about 170pC/N. Ferroelectric hysteresis loops are measured, and the remnant polarization (Pr) of the PZT ceramics pellet is about 25mC/cm2 and the coercive field (EC) is about 27kV/cm.

	Driving Audio Piezoelectric Transducers - Maxim/Dallas
		There are two possible ways to excite the audible PZT to produce sound; by driving it with a single-ended signal (i.e., 0V to +5V) or with a bipolar signal (i.e., -2.5V to +2.5V).
		From this test and similar test conducted on all PZTs studied, it appears for all practical purposes that the audible PZT impedance is purely capacitive and as such, current and voltage waveforms can be predicted by knowing the driving source voltage and source impedance.
		In integrated circuit design for a PZT driver, source impedance must be specified, since it is a major factor in the design of the output power stage for a PZT driver.

	HISTORY
		The Observatory participated in a program of determining longitude by comparing local time with that telegraphed from a clock at another fixed observatory, and thus exchanged time signals with other observatories and with the Coast Survey field parties.
		Beginning in 1934, the Observatory determined time with a photographic zenith tube (PZT), a specialized instrument that points straight upward toward the zenith and automatically photographs selected stars crossing the zenith.
		This gave a measure of the Greenwich Mean Time (now called Universal Time), the "time of day" based on the rotation of the Earth.
