The invention discloses a high-performance integral graphite sagger and a preparation method thereof. The preparation method comprises the following specific steps: S1, mixing crystalline flake graphite, a pre-sintered material, a mixed solution, amorphous alumina fine powder and carbon nanofibers to obtain a mixture; s2, placing the mixture in a mold, maintaining the pressure for a certain time, and demolding to obtain a sagger green body; and S3, the sagger green body is subjected to heat treatment and then cooled along with a furnace, and the high-performance integral graphite sagger is obtained. Wherein the pre-sintered material is prepared by the following method: mixing and ball-milling borax, carbon black, silicon powder and zirconium oxychloride to obtain a premix, then performing heat treatment on the premix in an inert gas atmosphere, cooling and grinding to obtain the pre-sintered material; the mixed solution is formed by mixing thermosetting phenolic resin, industrial alcohol and lanthanum nitrate. The prepared high-performance integral graphite sagger is high in strength, good in compactness and high in graphitization degree.
本发明公开了一种高性能整体石墨匣钵及其制备方法。制备方法具体步骤如下：S1、将鳞片石墨、预烧料、混合液、无定形氧化铝细粉和碳纳米纤维混合得混合料；S2、将混合料置于模具保压一定时间后脱模得匣钵生坯；S3、将匣钵生坯热处理后随炉冷却，即得高性能整体石墨匣钵；其中，所述预烧料由如下方法制备：将硼砂、炭黑、硅粉和氧氯化锆混合球磨得预混料，然后将预混料置于惰性气体氛围中热处理、冷却后研磨得预烧料；所述混合液由热固性酚醛树脂、工业酒精和硝酸镧混合而成。本发明所制备的高性能整体石墨匣钵强度高、致密性好和石墨化程度高。
