Example text

By filling these voids with smaller particles prior to sintering, the level of densification required can be reduced. This can be achieved by mixing two powders of different sizes where the smaller particles fill the gaps between the larger particles. Not only do the smaller particles help to increase the green density by filling in the voids, but they also help to accelerate the densification process due to their higher densification kinetics. Extreme care needs to be taken to ensure that a homogeneous distribution of the different sizes of particles is obtained; otherwise, some areas will sinter at a faster rate to other areas giving rise to differential strains and stresses which can cause deformation of failure of the body.

Therefore, voltage transformation can be accomplished by simply having appropriate structures within the transmission and reception parts of the device. 15). 15 Scanning electron micrograph and related schematic of a thick-film electrical transformer. The diaphragm to deformed by applying a voltage to the input electrodes. This caused piezoelectric material at the center of the diaphragm to be also strained which results in a (different) voltage being generated at the output electrodes. 7 Energy transmitters When energy or signals need to be transmitted through a solid obstacle, the most common solution is to drill a hole and pass a wire through the hole before sealing the gap.
