Claims (3)
- 규산나트륨과 해수를 중량비 1 : 50 내지 1:100으로 실온 및 정상압력에서 혼합시키고 교반하여 백색물질을 분리시키는 단계와, 상기 백색물질을 처리하여 분말형 백탄 생성물을 얻는 단계를 포함하는 것을 특징으로 하는 백탄의 제조방법.
- 제 1 항에 있어서, 규산나트륨과 해수를 혼합시키고 교반하기 전에 먼저 규산나트륨을 담수에서 용해시키는 것을 특징으로 하는 백탄의 제조방법.
- 제 1 항에 있어서, 규산나트륨과 해수의 반응결과로서 생성된 상기 백색물질은 또한 분말형 백탄 생성물로 처리되기 전에 담수로 세척되는 것을 특징으로 하는 백탄의 제조방법.
