Description
本特許出願は、2014年9月9日に出願された米国特許出願第14/481,570号及び2013年9月11日に出願された米国仮特許出願第61/876,696号の優先権及び利益を主張し、その両方の内容は、参照によりそれらの全体が本明細書に組み込まれる。
本要約は、以下の発明を実施するための形態にさらに説明される概念の選択を導入するために提供される。本要約は、特許請求される主題の主なまたは本質的な特徴を特定することを意図せず、また特許請求される主題の範囲を制限することを補助するものとして使用されることを意図しない。
本明細書で使用される、用語「炭酸塩系多結晶ダイヤモンド」は、炭酸塩材料の存在下で、個々のダイヤモンド粒子を、隣接するダイヤモンド結晶間で結晶間結合を生じさせる十分に高圧高温(HPHT)条件にさらして、ダイヤモンド−ダイヤモンド結合及び一緒に結合されたダイヤモンド粒間に分散された複数の間隙領域のネットワークまたはマトリックス相を形成することにより生成された得られた材料を指す。本開示の炭酸塩系多結晶ダイヤモンドは、多結晶ダイヤモンドまたはPCDと称され得るが、遷移金属溶媒触媒と共に形成された従来の方式で形成された多結晶ダイヤモンド(背景技術のセクションにおいて記載される)とは区別される。さらに、1つ以上の実施形態はまた、炭酸塩系多結晶ダイヤモンド体の分解を通して形成された酸化物系多結晶ダイヤモンドも指す。
