▎ 摘　　要

NOVELTY - High-strength heat accumulation carbon material with ≥90% degree of graphitization, overall orientation degree D(x)/D(z) is 100-500 and z-plane orientation degree D(z)/E(z) is 2-30, is claimed. The D(x) refers to the diffraction peak intensity of the crystal plane of the x-plane perpendicular to the force direction in the high-strength heat storage carbon material, D(z) is the diffraction peak intensity of the crystal plane parallel to the z-plane of the force direction in the high-strength heat storage carbon material and E(z) is the diffraction peak intensity of the crystal plane parallel to the z plane in the high-strength heat storage carbon material and D(x), D(z) and E(z) are all obtained byX-Ray diffraction analysis test. USE - The high-strength heat accumulation carbon material is useful in solid heat accumulation and/or heat dissipation field (all claimed). ADVANTAGE - The high-strength heat accumulation carbon material has a specific overall orientation and z-plane curvature, and excellent compressive strength while maintaining high molding density and heat conductivity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: Composition comprises 10-50 wt.% a heat-conducting filler, 45-80 wt.% agglomerant and 3-35 wt.% auxiliary agent; and Preparing high-strength heat accumulation carbon material, comprising (1) mixing the components in the high-strength heat storage carbon material composition to obtain a premix; (2) molding the premix to obtain a molding material; and (3) sintering and optionally graphitizing the molding material in an inert atmosphere to obtain the high-strength heat storage carbon material.
