Abstract:

The dielectric constants of lead azide in single crystal form were measured in the three crystallographic directions and found to be unusually large and highly anisotropic. The dielectric constants are fairly independent of temperature over the range of 100 K to 370 K and of frequency over the range of 100 to 1000 Hz. The dielectric constants of the azides of T1, Na, and K were also measured and compared to published values. Calculations taking into account the crystal structure of lead azide indicate that the observed anistropy arises from polarization of the azide molecule.
