HITZEBESTÄNDIGE, EXPANDIERTE GRAPHITPLATTEN UND VERFAHREN ZU DEREN HERSTELLUNG

摘要

An object of this invention is to provide an expanded graphite sheet which shows a low oxidative ablation factor in the air even when exposed to the air under high temperature conditions of 700 DEG C or higher for a long time and which is excellent in heat resistance and satisfactory in other properties required by this kind of expanded graphite sheet. The object of the invention can be achieved due to the presence of phosphorus pentoxide and phosphate in the sheet.
