칼사이트계 탄산칼슘의 제조방법
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음

Claims (2)

  1. 천연으로 산출되는 석회석을 사용하여 만든 수산화칼슘을 주성분으로 하는 물현탁액에 이산화탄소함유 가스를 응응시켜 칼사이트(calcite)계 탄산칼슘을 제조하는 칼사이트계 탄산칼슘의 제조방법에 있어서 상기 탄산화 반응시에 Sr 또는 Ba, 혹은 이들 양자를 부가한 조건아래, 상기 탄산화반응을 완결케하는 것을 특징으로 하는 칼사이트계 탄산칼슘의 제조방법.
  2. 제1항에 있어서 만들어진 탄산칼슘에 대하여 Sr 또는 Ba, 혹은 이들 양자의 부가량을 0.005％이상으로하고 또 그 첨가량과 원료석회석중에 함유되는 Sr분 또는 Ba과의 합계량은 Sr가 0.05이상 또는 Ba가 0.01％이상으로 되어진 칼사이트계 탄산칼슘의 제조방법.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
