Abstract

This study aimed to investigate the differences in the commercial powder products of the Yeongdong illite based on sales specifications, specifically examining the mineralogical composition, particle size, and chemical composition according to mesh size. The goal was to understand the characteristics of illite powder products and utilize them as a mineralogical database for exploring various applications. Commercial illite powder samples obtained from two mines were subjected to various experiments, including X-ray diffraction (XRD) analysis, laser diffraction particle size analysis, and scanning electron microscopy analysis, X-ray fluorescence analysis. The XRD analysis revealed that the illite powder products from the two mines mainly consisted of illite/muscovite, quartz, and feldspar, indicating similar constituent minerals matching with those of ores for each mine. Laser diffraction particle size analysis indicated the difference in particle size distribution depending on the product specifications, with particle size uniformity tending to increase with increasing mesh sizes. Scanning electron microscopy analysis showed variations in particle shape and size based on specifications. The size of illite particles did not vary significantly with product specifications, with noticeable changes observed mainly in the particle sizes of quartz and feldspar. Furthermore, although there were some differences in chemical composition among the samples from different mines, no significant variations were observed according to specifications. Based on these results, when considering the application of commercial illite powder, it is essential to carefully select it with the consideration of its specifications to account for characteristic variations. The findings of this study present support the great potential of various application fields of commercial illite powder, contributing to industrial utilization and the development of new technologies.

본 연구는 상업용 영동 일라이트 분말 제품의 판매 규격, 즉 메쉬(mesh)에 따른 구성광물, 입도, 화학조성의 차이를 조사하여, 일라이트 분말 제품의 특성을 이해하고 다양한 활용 분야를 개척하기 위한 광물학적 데이터베이스로 활용하고자 하였다. 충청북도 영동군의 광산을 보유한 두 곳의 회사에서 제공받은 상업용 일라이트 분말 시료를 X-선 회절 분석, 레이저 회절 입도 분석, 주사전자현미경 분석, X-선 형광 분석을 이용해 조사하였다. X-선 회절 분석 결과, 두 광산의 일라이트 분말 제품에는 주로 일라이트 및 백운모, 석영, 사장석이 존재하며, 이는 각 광산의 광석의 구성광물과 일치하는 경향을 보인다. 레이저 회절 입도 분석에서는 제품 규격에 따라 입자 크기의 차이가 나타났으며, 입도의 균일성은 메쉬가 높아질수록 증가하는 경향을 보였다. 주사전자현미경 분석에서는 입자의 형태와 크기가 규격에 따라 다르게 나타났다. 일라이트 입자의 크기는 제품의 규격 메쉬에 따른 차이가 크게 없으며, 주로 장석 및 석영의 입자 크기에 변화가 발생하는 것으로 나타났다. 또한, 시료의 화학 조성은 광산마다 다소의 차이가 있으나, 규격별로 큰 차이는 나타나지 않았다. 이러한 결과를 토대로, 상업용 일라이트 분말의 활용 분야를 고려할 때 규격에 따른 특성 변화를 고려하여 선택하는 것이 중요하다. 본 연구 결과는 상업용 일라이트 분말의 다양한 응용 가능성을 제시하며, 산업적 활용 및 새로운 기술 개발에 기여할 것으로 기대된다.
