An electronic device, such as a Surface Wave, Bulk Wave or pyroelectric device, exploiting the polar nature of an active material in which the active material is lithium tetraborate or a closely related compound for example one which is slightly deficient in Lithium or Boron e.g. (Li.sub.2.-+..delta.1)B.sub.4 O.sub.7 or Li.sub.2 (B.sub.4.-+..delta.2)O.sub.7 where .delta..sub.1 and .delta..sub.2 are small numbers.

Application of lithium tetraborate to electronic devices
