Description

사플루오르화 규소의 제조방법
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
첨부한 도면은 규소-불소를 포함하는 기체로부터 순수한 사플루오르화 규소를 제조하는 공정을 나타내는 흐름도이다.

Claims (2)

  1. 규소-불소를 포함하는 기체를 가수분해시키는 단계, 가수분해물을 플루오르화 나트륨, 플루오르화 칼륨 또는 플루오르화바륨과 반응시키는 단계, 그리고 얻은 반응생성물을 열분해시켜 이로써 사플루오르화 규소를 형성시키는 단계로 이루어지는 것을 특징으로 하는 사플루오르화 규소의 제조방법.
  2. 제1항에 있어서, 열분해의 동안에 생기는 플루오르화 금속을 재순환시키는 것을 특징으로 하는 사플루오르화 규소의 제조방법.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
