Abstract

Silica nanopowder from domestic siliceous mudstone was synthesized by taking three steps: first, sodium silicate was synthesized by the dissolution of amorphous silica from the siliceous mudstone using aqueous sodium hydroxide solution. Then aqueous silicic acid solution less than 50 ppm in sodium concentration was prepared from the sodium silicate by ion exchange method. Finally, the aqueous silicic acid was oxidized using a spray flame reactor to synthesize amorphous silica nanoparticles with average primary particle diameter of 9 to 57 nm.

국내 규질이암으로부터 3단계의 주요과정을 거쳐 실리카 나노분말을 제조하였다. 먼저 규질이암 중의 비정질 실리카를 수산화나트륨 수용액으로 용해하여 규산나트륨 수용액을 제조하였다. 그 후, 규산나트륨 수용액으로부터 이온교환수지법을 사용하여 나트륨 이온의 농도가 50 ppm이하인 규산 수용액을 합성하였다. 마지막으로 규산 수용액을 화염 속으로 분무하여 열분해 반응시켜 평균 기본 입자크기가 9 ~ 57 nm인 비정질 실리카 나노분말을 제조하였다.
