Beschreibung
Zusammenfassung:	Powder for a sintered body according to an aspect of the present invention comprises: metal-doped carbon-based powder in which metal is included in a space between carbon atom layers of the carbon-based powder; and diamond powder. In the powder for a sintered body according to one aspect of the present invention, as carbon-based powder and diamond powder formed by diffusion or penetration of metal atoms between carbon atom layers formed by crystallization of carbon atoms are uniformly dispersed, the carbon of carbon-based powder generated during high-temperature and high-pressure sintering forms diamond crystals, to form a uniform bond of the diamond powder. 본 발명의 일 측면에 따른 소결체용 분말은, 탄소계 분말의 탄소원자층간 공간에 금속이 포함되는 금속도핑된 탄소계 분말; 및 다이아몬드 분말;을 포함하는 것을 특징으로 한다.
