Quarz ist optisch einachsig positiv, mit den Brechungsindizes w = 1,5442 und e = 1,5533. Nicht selten wachsen links und rechtsdrehende Quarze zu sogenannten „Zwillingen" in einer hexagonalen Struktur zusammen, die nach oben in einer Spitze ausläuft. Quarz bildet keine Spiegelflächen in der Symmetrie.

For example, the melting point of crystalline solid Quartz is 1550 o C. For amorphous solids, the change of phase is slow and occurs over a range of temperatures as shown from T1 to T2. It goes from the solid state to a glassy state and then to a rubbery state. The amorphous solid in the glassy state is hard, rigid and brittle. On further heating, it attains a rubbery state. It is the rubbery ...

Piezoelectricity (/ ˌ p iː z oʊ, ˌ p iː t s oʊ, p aɪ ˌ iː z oʊ/, US: / p i ˌ eɪ z oʊ, p i ˌ eɪ t s oʊ/) is the electric charge that accumulates in certain solid materials—such as crystals, certain ceramics, and biological matter such as bone, DNA, and various proteins—in response to applied mechanical stress. The word piezoelectricity means electricity resulting from ...

Quartz, also known as rock crystal, is the crystalline form of SiO 2 belonging to the trigonal system. A quartz plate is cut from a crystal in a specified direction to form a plate or rod, provided with electrodes and a fulcrum, and connected in an oscillator circuit. Applying an voltage causes stress or strain to occur in the plate at the same frequency as the applied voltage, and if the ...

· Crystalline silica refers to a chemical compound, silicon dioxide (SiO 2), that is most commonly found in nature as quartz but sometimes occurs as cristobalite or, rarely, as tridymite. Quartz accounts for the overwhelming majority of naturally occurring crystalline silica and is present in varying amounts in almost every type of mineral. Quartz is found in rocks such as granite, sandstone ...

For example, if the crystal load capacitance is 15pF, and assuming Cstray=2pF, then: CX1 = CX2 = 2(15pF 2pF) = 26pF . It is difficult to know exactly what the stray capacitance is, but if you find the oscillation frequency is too high, the load capacitor values can be increased. If the frequency is too low, the load capacitors can be decreased.
