- Abstract
Applied materials research and testing often involve measurements of material properties such as dielectric permittivity, impedance, piezoelectric coefficient, and pyroelectric current under non-ambient conditions and a controlled atmosphere. This requires simultaneous operation of multiple types of equipment and a controlled atmosphere for non-ambient conditions with computer-controlled data collection and operation. Here, we present the design and fabrication of a cost-effective measurement probe and measurement furnace with a capability of 1000°C under a controlled gas atmosphere. The setup, when used in tandem with an LCR meter or a source measure unit, can perform impedance and pyroelectric current measurements up to a temperature of 1000°C under a controlled atmosphere. We demonstrate the measurement capabilities in well-known ferroelectrics and oxide ion conductors including BaTiO3, (La0.9Sr0.1)(G0.9Mg0.1)O3-δ, Na0.5Bi0.5TiO3, and Pb(Zr, Ti)O3.
