Claims (1)
- 염화제1철 수용액에 알칼리 수용액을 당량이하로 첨가하여 수산화제1철을 제조한 다음 이를 산화시켜 레피도크로사이트 종결정을 제조하고, 그 종결정을 성장시켜레피도크로사이트를 제조하는 습식산화법에 있어서, 상기 염화제1철 수용액에 알칼리 수용액을 첨가하여 수산화제1철을 제조한 후 이를 산화시켜 레피도크로사이트 종결정을 생성하는 경우, 수산화제1철의 산화속도를 0.4-1.6mol/min 조절하여 종결정을 생성하는 단계;및 상기 종결정 생성후, 반응현탁액의 온도를 일정온도로 승온한 다음 산화반응시켜 결정을 성장시키되, 수산화 제1철의 산화속도를 0.15-0.4mol/min로 조절하여 종결정을 성장시키는 단계; 를 포함하는 레피도크로사이트 제조방법.
