METHOD OF PRODUCING GRAPHITE MATERIAL
To provide a graphite material of improved oxidative wear resistance, and a method of producing the same.SOLUTION: There is provided a graphite material prepared by immersing a graphite material including Fe as a trace impurity element having been reduced to 1 mass.ppm or less, in a phosphate solution containing one species or two or more species selected from boron hydroxide, aluminum hydroxide and silicon hydroxide as a main component to impregnate the pores of the graphite material with the metal hydroxide, and thereafter converting the metal hydroxide to a corresponding metal oxide by a drying/heating treatment so that the pores are filled/encapsulated with the metal oxide phase. A method of producing the same is also provided.SELECTED DRAWING: Figure 4
【課題】耐酸化損耗性を向上させた黒鉛材料、およびその製造方法を提供する。【解決手段】微量不純物元素であるＦｅの含有量を１massppm以下に減少させた黒鉛材料に対し、Ｂ，Ａｌ，Ｓｉから選択された一種又は二種以上の水酸化物を主成分とするリン酸塩溶液中に浸漬することにより金属水酸化物を黒鉛材料の細孔に含侵させ、次いで、乾燥・加熱処理により金属水酸化物を金属酸化物相として細孔に充填・封止した黒鉛材料及びその製法。【選択図】図４
