Description
すなわち、本発明は、上記課題を解決するために、以下の手段を提供する。
金属のタンタルに黒鉛を接触させて加熱し、加熱時間を変化させて炭化度の異なる炭化タンタルを複数作製した。得られた炭化タンタルは、それぞれ色彩に違いがあった。得られた炭化タンタルをX線回折装置(XRD)で分析し、結晶の格子定数を測定した。色彩は、コニカミノルタ社製SPECTROPHOTOMETER CM−2600dを用いて、SCI方式で測定した。
実施例2は、色彩の評価を写真撮影によって行った点が実施例1と異なる。写真撮影の条件は、光源を1個とし、光源と測定面のなす傾斜角はおおよそ5°〜80°の範囲内で4点測定し、その平均値を採用した。
