The thermal expansion coefficient of solids gives useful information about the anharmonicity of the vibrations in the asymetric binding potential and about the nature of phase transitions. Therefore it was built a capacitive dilatometer for the low temperature region, because this type provides the highest sensitivity of all known measuring methods of thermal expansion.1
