MORGAN ADVANCED MATERIALS: Ceramic Components
This company recently announced the launch of its improved range of stave-shaped ceramic components for the defense and commercial sonar sectors. Sonar systems, used by many of the world’s navies, contain ceramic materials because they offer solutions where high acoustic transmission properties are required in low-frequency environments. These new products are reportedly operable at extremely low depths, and continue to work even in the most severe bath thermal conditions, where water temperature falls as water depth increases.
To produce low-frequency active sonar, a range of “stave” components is available, assembled together to create large ceramic rings and used as underwater projector transducers. To combat size restrictions, electrodes are positioned between each ceramic segment, with the segments then poled around the circumference. This arrangement is also known as a segmented construction and can allow for very large rings to be constructed, although careful control of the tolerance is necessary to obtain a well-consolidated assembly with uniform joints.
