Abstract

본 발명은 광범위하게 열에 안정하고 조밀한 전기 전도성 다이아몬드 콜팩트를 제조하는 방법에 관한 것이다.
본 방법은 약 1200℃를 실질적으로 넘지 않는 온도 및 약 45Kbar를 실질적으로 넘지 않는 압력을 포함하는 조건하에 붕소의 존재 하에서 다이아몬드 결정괴를 실리콘 침투제에 침투시킴을 포함한다. 생성된 콤팩트는 다이아몬드 대 다이아몬드 결합을 함유한다. 붕소는 붕소가 도핑된 다이아몬드의 형태로 제공될 수 있다. 다른 방법으로, 붕소―실리콘 합금을 붕소가 도핑되거나 또는 도핑 되지 않는 다이아몬드를 침투시키는데 사용할 수 있다. 또한, 침투시키기 위해 붕소를 실리콘과 함께 원자 붕소 또는 B₄C로 첨가할 수 있다. 다른 방법으로, 붕소 금속촉매+실리콘 합금을 붕소가 도핑된 다이아몬드에 사용할 수 있다. 상기 기법의 조합도 또한 사용할 수 있다. HP/HT공정에서, 실리콘은 다이아몬드 분말괴에 침투하여 실리콘과 다이아몬드-탄소의 반응에 의해 실리콘 카바이드로 이루어진 망상구조를 형성한다. 이 반응은 붕소가 도핑된 다이아몬드 또는 다이아몬드를 갖는 붕소 화합물로 이루어진 소결체 또는 실리콘 카바이드와 실리콘의 망상구조를 남긴다.
