• Silica Statistics and Information

    Industrial sand and gravel, often called "silica," "silica sand," and "quartz sand," includes sands and gravels with high silicon dioxide (SiO2) content. These sands are used in glassmaking; for foundry, abrasive, and hydraulic fracturing (frac) appliions; and for many other industrial uses. The specifiions for each use vary, but silica resources for most uses are

  • How to calculate the value of crystal load capacit ...

    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.

  • Quartz

    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 ...
