摘要	The M-Cl (M=Fe, Co, Ni) boracites are prepared by a procedure consisting of solution mixing, evaporating to dryness, grinding and heating reaction in N-2 atmosphere. The lattice parameter and the phase transition temperatures of the boracites Co3B7O13Cl and Ni3B7O13Cl are investigated by means of X-ray diffraction, transmission electron microscopy and differential scanning calorimetry. There are three reversible phase transitions in the Co-Cl boracite and one phase transition in the Ni-Cl boracite above room temperature. Temperature dependences of dielectric loss of M-Cl (M=Fe, Co, Ni) boracites are studied by the rectangular cavity perturbation method at a microwave frequency of 2.45 GHz. The ferroelectric property at room temperature of the Co3B7O13Cl is demonstrated. (C) 2002 Published by Elsevier Science B.V.
