摘要： 본 발명은 고순도로 정련된 금속 니오븀의 잔류 불순물인 산소 및 질소를 간접적으로 간단히 정량할 수 있는 방법으로, 보다 상세하게는 금속 니오븀의 전기 비저항치가 잔류 불순물인 산소 및 질소의 농도에 비례하는 관계를 이용하여 금속 니오븀의 전기저항치를 측정만으로 산소와 질소의 농도를 간접적으로 알아낼 수 있는 방법에 관한 것이다.
본 발명의 특징은 금속의 고유 성질인 비저항을 이용하여 금속 내부의 잔존 불순물의 농도를 간접적으로 알아내는 단계와, 니오븀 인고트의 불순물 농도 간접측정에 이용하는 단계와, 니오븀 인고트의 전기저항을 측정하는 단계와, 니오븀 인고트의 불순물과 비저항의 관계(ρ = 13.14+(2.68×10
-3 μΩ·cm/mass ppm) Co+
N )를 확립하여 불순물 농도를 간접적으로 산출하는 단계를 포함하는 니오븀 불순물 농도 정량 방법에 있다.
이러한 본 발명 방법에 따른 니오븀의 불순물(산소 및 질소)농도의 정량들은 실제 분석값에 거의 근사한 값으로 나타나게 된다.
