Abstract

The pyroelectric coefficient (p) of the mm2 phases of Fe-I and Cu-Cl boracites were measured from 20 Deg up to their Curie temperatures by the quasistatic technique of R. L. Byer and C. B. Roundy (1972). For Fe-I boracite at 20 and 63 Deg, p = 0.02 * 10-8 and 0.1 * 10-8 C/cm2 K, resp. For Cu-Cl boracite at 20 and 86 Deg, p = 0.55 * 10-8 and 2.5 * 10-8 C/cm2 K, resp. A dynamic measurement method applied to Cu-Cl boracite at 20 and 60 Deg gave p = 0.36 * 10-8 and .apprx.1.3 * 10-8 C/cm2 K, resp.
