Abstract： |
The invention relates to the ternary compound magneto-electric material by use of the organic macromolecule as the agglomerant as well as its preparation method.With the organic macromolecule being as the agglomerant the piezoelectric ceramic(such as lead zirconate titanate etc.)and the magnetostriction material(such as terbium-dysprosium-iron alloy)are taken shape by hot pressing at low temperature.The magneto-electric compound material can be made by the method.Comparing the prior art,the invention possesses the advantages of simple process,good mechanical characters of the material and high magneto-electric transformation factor.The hotpressing technique provides the features of low pressing temperature(about 120-200 deg.C),easy to change the magneto-electric characters by changing the sequence for adding the constituent and the relative content. |
