WebA thickness shear mode crystal is supported by the edges at an approximate null or zero node to avoid interfering with the vibration. A typical 1 MHz crystal, due to its size, might be held by tension wires at several points about the surface edge. A 10 MHz unit being smaller could be supported at two points on a ceramic header. The most common material for oscillator crystals is quartz. At the beginning of the technology, natural quartz crystals were used but now synthetic crystalline quartz grown by hydrothermal synthesis is predominant due to higher purity, lower cost and more convenient handling. One of the few remaining uses of natural crystals is for pressure transducers in deep wells. During World War II a…
