随着S, O等元素的增加, 石墨棱面的界面能逐渐降低, 有利于片状石墨的生长.球化剂Ce, Mg等元素与S, O反应后, 重新使石墨棱面的界面能提高, 有利于球状石墨的成长.","authors":[{"authorName":"朱定一","id":"8d4f161a-ff06-448f-8052-094b8ba7710c","originalAuthorName":"朱定一"},{"authorName":"关翔锋","id":"410f8b1b-0ff5-456b-b977-75869bde29e9","originalAuthorName":"关翔锋"},{"authorName":"陈丽娟","id":"ceaa2451-7a35-47f5-b4ea-e1e215b3bae0","originalAuthorName":"陈丽娟"},{"authorName":"汤伟","id":"a7d254b0-2748-44fc-99fb-c16f74e8832d","originalAuthorName":"汤伟"}],"doi":"10.3969/j.issn.0258-7076.2005.02.007","fpage":"156","id":"a2a6c152-33a8-4b1f-95c5-ae6c75e2c82a","issue":"2","journal":{"abbrevTitle":"XYJS","coverImgSrc":"journal/img/cover/XYJS.jpg","id":"67","issnPpub":"0258-7076","publisherId":"XYJS","title":"稀有金属"},"keywords":[{"id":"ec792901-5ade-4be4-a3c5-32f8cce6c244","keyword":"石墨形貌","originalKeyword":"石墨形貌"},{"id":"bc7b978d-24b1-4b5d-81bc-581315cd2b51","keyword":"<span
