Description
マンガン源化合物としては、ＭｎＯ２、Ｍｎ２Ｏ３、Ｍｎ３Ｏ４、ＭｎＯＯＨ、ＭｎＣＯ３、Ｍｎ（ＮＯ３）２、ＭｎＳＯ４、Ｍｎ（ＯＣＯＣＨ３）２、Ｍｎ（ＯＣＯＣＨ３）３、ＭｎＣｌ２、ＭｎＣｌ ３及びクエン酸マンガン等が挙げられる。このうち、ＭｎＯ２、Ｍｎ２Ｏ３、Ｍｎ３Ｏ４又はＭｎＯＯＨ、特にＭｎＯ２、Ｍｎ２Ｏ３又はＭｎ３Ｏ４が好ましい。
圧縮剪断応力を加える処理とは、（Ａ）、（Ｂ）及び（Ｃ）の各成分を所定の比率で配合したものに、特開平１１−１５４５１５号公報や特開２０００−１２３８７６号公報に記載されている方法と同じく、圧縮及び剪断応力を加える操作をいう。これにより圧縮された配合物は一体化されると共に、一体化したものの一部が剪断応力により削られて微粉となり、これが再び一体化された粒子に結合されるという、いわゆるメカノフュージョンが発現されるものと考えられる。この処理は、例えば、「メカノフュージョンシステム」（ホソカワミクロン社製）、又は「ハイブリダイゼーションシステム」（奈良機械製作所社製）等を用いて行うことができる。
