SINTERED MATERIAL AND ELECTRET MATERIAL
PROBLEM TO BE SOLVED: To provide a sintered material that has a composition and crystalline structure similar to a hexagonal crystal apatite which is suitable for use in electret material or the like, and to provide an electret material using said sintered material as well as having a surface potential after stabilization of 1300 V or more.SOLUTION: The sintered material includes a sintered material 12 having a composition and crystalline structure similar to a hexagonal crystal apatite at least comprising a first metallic ion as a cation, and a hydroxide ion and phosphate ion as an anion, and in which the sintered material 12 furthermore comprises a second metallic ion different from the first metallic ion.SELECTED DRAWING: Figure 1
【課題】エレクトレット材等に用いて好適な六方晶アパタイト類似の組成と結晶構造を有する焼結体と、該焼結体を用い、且つ、安定後の表面電位が１３００Ｖ以上のエレクトレット材を提供する。【解決手段】カチオンとしての第１金属イオンと、アニオンとしての水酸化物イオン及びリン酸イオンとを少なくとも含む六方晶アパタイト類似の組成と結晶構造を有する焼結体１２を具備し、さらに、該焼結体１２が前記第１金属イオンとは異なる第２金属イオンを含む。【選択図】図１
