Assertion: quartz's expansion coefficient | /r/HasProperty | anisotropic
Facets:
Source sentences:
text: However, the pyroelectricity observed in quartz is simply a side effect of its piezoelectricity and the fact that its thermal expansion coefficient is anisotropic (see under "Mechanical Properties"): a crystal that is heated up quickly will suffer the same stress and strain as if mechanical pressure was applied.
text: The thermal expansion coefficient is also anisotropic, and is smaller parallel to the c axis: if you heat up a crystal, it will get more elongated.
