crystalline phases. Ceramics are often semi-crysta lline. Polymers are generally non-crystalline. The table shown reports the expected behaviors above and below the Tg for materials as a function of the Tg [CLICK] and room temperature. [CLICK] Most metals and [CLICK] almost all ceramics are usually well below their Tg at room temperature.

For example, for a good ma rgin of safety, it would be nice to have the circui t oscillate with at least tw ice the maximum specified cr ystal resistance. The size of the potentiometer required for the test will increase as the crystal frequency decreases (i.e., 1 kΩ for a
