Abstract
산지가 다른 22종류의 국산무연탄에 함유되어 있는 흑연의 함량을 internal standard method와 direct method로 정량분석하였다. 두 방법으로 실험한 분석결과는 약 ±3%내에서 잘 일치하였다. 각 시료중에 함유되어 있는 무정형탄소와 흑연성탄소의 함량비는 지역별로 다소 차이가 있으며 문응지구가 14∼24%, 대천지구가 12∼14%, 강원지구가 3∼5%로서 강원지구에서 산출되는 무연탄중의 흑연함량이 가장 적음을 알 수 있다.

Twenty two Korean anthracites obtained places were quantitatively analyzed by the internal standard method and direct method. The range of deviation the results obtained by the two methods is about ±3%. The ratio of graphite to amorphous carbon contents of each samples is very different according to the district of coal mine. The ratio of graphite contents in Mun Kyung district is from 14 to 24 %, Dae Chun district is from 12 to 14 % and Kang Won district is from 3 to 5 %. We have known athat the anthracites of Kang Won district are the least graphite contents.
