Beschreibung
Zusammenfassung:	Provided is a method for preparing iridium chloride hydrate, comprising: a mixing step of preparing a mixture of iridium metal powder and an alkali metal compound; a calcination step of calcining the mixture to produce an iridium oxide containing alkali; an aqueous hydrochloric acid solution washing step of washing the iridium oxide containing alkali with an aqueous hydrochloric acid solution to obtain an iridium oxide; and a hydrochloric acid dissolution step of dissolving the iridium oxide in hydrochloric acid under pressure and then making a reaction. 이리듐 금속 분말과 알칼리 금속 화합물의 혼합물을 준비하는 혼합 단계, 혼합물을 소성하여 알칼리가 포함된 이리듐 산화물을 제조하는 소성 단계, 알칼리가 포함된 이리듐 산화물을 염산 수용액으로 세척하여 이리듐 산화물을 얻는 염산 수용액 세척 단계, 그리고 이리듐 산화물을 가압하에서 염산에 용해한 후 반응시키는 염산 용해 반응 단계를 포함하는, 이리듐 클로라이드 수화물의 제조 방법을 제공한다.
