HEAT STORAGE GRAPHITE HAVING LOW DEGREE OF ORIENTATION, COMPOSITION FOR PREPARING HEAT STORAGE GRAPHITE HAVING LOW DEGREE OF ORIENTATION, AND METHOD THEREFOR
Provided a heat storage graphite having a low degree of orientation, a composition for preparing heat storage graphite having a low degree of orientation, and a method for preparing heat storage graphite having a low degree of orientation. The heat storage graphite comprises, in terms of the total mass of the heat storage graphite, 65-85 wt % of dispersed-phase graphite and 15-35 wt % of continuous-phase graphite, wherein the dispersed-phase graphite is spherical graphite, and the sphericity of the spherical graphite is 0.5-1; the ratio of the vertical thermal conductivity/plane-oriented thermal conductivity of the heat storage graphite is 0.4-0.8; and the plane-oriented thermal conductivity of the heat storage graphite is 50-150 W/mK. The heat storage graphite has the advantages of a low degree of orientation and high plane-oriented thermal conductivity.
