The dominant type of  defect  of concern in quartz crystals is the substitution of an  Al(III)  for a  Si(IV)  atom in the  crystal lattice . The aluminium ion has an associated interstitial charge compensator present nearby, which can be a  H +  ion (attached to the nearby oxygen and forming a  hydroxyl group , called Al−OH defect),  Li +  ion,  Na +  ion,  K +  ion (less common), or an  electron hole  trapped in a nearby oxygen atom orbital. The composition of the growth solution, whether it is based on lithium or sodium alkali compounds, determines the charge compensating ions for the aluminium defects. The ion impurities are of concern as they are not firmly bound and can migrate through the crystal, altering the local lattice elasticity and the resonant frequency of the crystal. Other common impurities of concern are e.g. iron(III) (interstitial), fluorine, boron(III), phosphorus(V) (substitution), titanium(IV) (substitution, universally present in magmatic quartz, less common in ...

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  and for some time afterwards, natural quartz was considered a  strategic material  by the USA. Large crystals were imported from Brazil. Raw "lascas", the source material quartz for hydrothermal synthesis, are imported to USA or mined locally by Coleman Quartz. The average value of as-grown synthetic quartz in 1994 was  60  USD /kg. [23] Types [ edit ] Two types of quartz crystals exist: left-handed and right-handed. The two differ in their  optical rotation  but they are identical in other physical properties. Both left and right-handed crystals can be used for oscillators, if the cut a...

For crystals operated at series resonance or pulled away from the main mode by the inclusion of a series inductor or capacitor, significant (and temperature-dependent) spurious responses may be experienced. Though most spurious modes are typically some tens of kilohertz above the wanted series resonance their temperature coefficient is different from the main mode and the spurious response may move through the main mode at certain temperatures. Even if the series resistances at the spurious resonances appear higher than the one at wanted frequency a rapid change in the main mode series resistance can occur at specific temperatures when the two frequencies are coincidental. A consequence of these activity dips is that the oscillator may lock at a spurious frequency at specific temperatures. This is generally minimized by ensuring that the maintaining circuit has insufficient gain to activate unwanted modes. Spurious frequencies are also generated by subjecting the crystal to vibration. ...

The crystal oscillator circuit sustains oscillation by taking a voltage signal from the quartz  resonator , amplifying it, and feeding it back to the resonator. The rate of expansion and contraction of the quartz is the  resonant  frequency, and is determined by the cut and size of the crystal. When the energy of the generated output frequencies matches the losses in the circuit, an oscillation can be sustained. An oscillator crystal has two electrically conductive plates, with a slice or tuning fork of quartz crystal sandwiched between them. During startup, the controlling circuit places the crystal into an  unstable equilibrium , and due to the  positive feedback  in the system, any tiny fraction of  noise  is amplified, ramping up the oscillation. The crystal resonator can also be seen as a highly frequency-selective filter in this system: it only passes a very narrow subband of frequencies around the resonant one, attenuating everything else. Eventually, only the resonant frequency...

Operation [ edit ] A  crystal  is a  solid  in which the constituent  atoms ,  molecules , or  ions  are packed in a regularly ordered, repeating pattern extending in all three spatial dimensions. Almost any object made of an  elastic  material could be used like a crystal, with appropriate  transducers , since all objects have natural  resonant  frequencies of  vibration . For example,  steel  is very elastic and has a high speed of sound. It was often used in  mechanical filters  before quartz. The resonant frequency depends on size, shape,  elasticity , and the  speed of sound  in the material. High-frequency crystals are typically cut in the shape of a simple rectangle or circular disk. Low-frequency crystals, such as those used in digital watches, are typically cut in the shape of a  tuning fork . For applications not needing very precise timing, a low-cost  ceramic resonator  is often used in place of a quartz crystal. When a crystal of  quartz  is properly cut and mounted, it ca...

A crystal oscillator is an  electric oscillator  type circuit that uses a piezoelectric resonator, a crystal, as its frequency-determining element.  Crystal  is the common term used in electronics for the frequency-determining component, a wafer of  quartz crystal  or ceramic with electrodes connected to it. A more accurate term for it is  piezoelectric resonator . Crystals are also used in other types of electronic circuits, such as  crystal filters . Piezoelectric resonators are sold as separate components for use in crystal oscillator circuits. They are also often incorporated in a single package with the crystal oscillator circuit. History [ edit ] 100 kHz crystal oscillators at the US National Bureau of Standards that served as the frequency standard for the United States in 1929 Very early Bell Labs crystals from Vectron International Collection Piezoelectricity  was discovered by  Jacques  and  Pierre Curie  in 1880.  Paul Langevin  first investigated quartz resonators for use i...
