WebThese are typical properties. In fact, properties of ceramics and glass can be tailored to specific applications by modifying composition, including creating composite materials with metals and polymers, and by changing processing parameters. Typical properties of ceramics. High hardness. High elastic modulus. Webare called the motional parameters of the crystal, and C0 is the shunt capacitance. C0 is real—it can actually be measured with a simple capacitance meter. The motional arm parameters, on the other hand, are equivalents and not simple to measure. How much the frequency of the crystal is pulled or deviated will depend on the ratio of C0/C1.
