COMPOSITE MATERIAL, POWDER MATERIAL, ABRASIVE MATERIAL AND METHOD FOR PRODUCING COMPOSITE MATERIAL
To provide a composite material, powder material containing the composite material and an abrasive containing the composite material, which have obtained a surface modification effect by thinly covering oxide ceramic, and a method for producing the composite material.SOLUTION: The composite material disclosed herein is a composite material comprising a non-oxide ceramic or diamond, and a metal or semi-metal oxide ceramic adhered to a surface of the non-oxide ceramic or diamond, wherein the oxide ceramic is an aggregate of a plurality of particles, has pores between the particles of the oxide ceramic, and has a maximum peak pore diameter of 5 nm or less in a differential pore volume distribution of the oxide ceramic determined by a non-localized density functional (NLDFT) method.SELECTED DRAWING: Figure 2
【課題】酸化物セラミックスを薄く被覆することにより、表面改質効果を得た複合材料、該複合材料を含む粉体材料ならびに該複合材料を含む砥材、そして該複合材料の製造方法の提供を目的とする。【解決手段】ここに開示される複合材料は、非酸化物セラミックスまたはダイヤモンドと、上記非酸化物セラミックスまたは上記ダイヤモンドの表面に付着した金属または半金属の酸化物セラミックスと、を含む複合材料であって、上記酸化物セラミックスは、複数の粒子の集合体であり、上記酸化物セラミックスの上記粒子間に細孔を有し、非局在化密度汎関数（ＮＬＤＦＴ）法により求めた上記酸化物セラミックスの微分細孔容積分布における最大ピーク細孔径が、５ｎｍ以下であることを特徴とする。【選択図】図２
