Abstract

Pyroelectric, piezoelectric and dielectric properties of single crystal Li₂B₄O₇ (LTB) are measured in the temperature range from 50°C down through — 150°C. At room temperature LTB has dielectric constant K₃- 10 (at 100 KHz) and dielectric tan δ- 1 (10 KHz). At liquid nitrogen temperatures, the tan δ decreased to - 10^-3. Pyroelectric coefficient at room temperature measured -30 μC/m²-K which increased to — 120 μC/m²-K at — 150°C and showed the pyroelectric figure of merit piK comparable to the value obtained on TGS at room temperature. Primary and secondary components of pyroelectricity are separated and the results suggest that the major contribution comes from the primary effect in Li₂B₄0₇. Piezoeleotric measurements show high values of g₃₃ = 210X 10^-3 V-m/N and g_h = 100X 10^-3 V-m/N indicating potential application of Li₂B₄O₇ in the area of pressure sensors.
