Claims (1)
전복, 굴, 조개등의 패각을 염산에 넣어 침전시킨 후 정수로 세척시켜 900℃의 온도로 4시간 가열하고 400메시로 분쇄시킨 다음 분쇄된 산화칼슘을 중화탱크에 넣고 메칠오렌지 시약을 가해 포화탄산나트륨으로 중화시킨 뒤 옥산나트륨을 가하여 고순도의 탄산 칼슘을 제조함을 특징으로 하는 패각을 주원료로 한 탄산칼슘의 제조방법.Shells of abalone, oysters, shellfish, etc. were precipitated by hydrochloric acid, washed with purified water, heated to 900 ° C for 4 hours, pulverized with 400 mesh, crushed calcium oxide was placed in a neutralization tank, and methyl orange reagent was added to the saturated sodium carbonate. Method of producing calcium carbonate with a shell as the main raw material, characterized in that to produce a high-purity calcium carbonate by neutralizing with sodium oxate.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
