CERAMIC THERMALLY-COMPENSATED RESONATOR

摘要

The resonator has a deformable body i.e. bar, whose core (8) is made of ceramic. A portion of the body comprises an electrically conductive coating (2), where Young modulus variations of the coating are based on temperature and have a sign opposed to Young modulus variations of ceramic used for the core such that the resonator has a temperature-based frequency variation of a zero order. The core of the body comprises glass, metal glass, technical ceramics or ceramic glass. The body comprises a section in form of a quadrilateral, where faces of the body are identical.
