Abstract
본 발명은 지르콘(ZrSiO4) 샌드로부터 지르코니아(ZrO2)를 제조하는 방법에 관한 것으로서, 종래방법보다 제조공정이 간단하고 경제적이며, 환경오염물질이 발생하지 않는 열프라즈마를 이용한 지르코니아의 제조방법을 제공하는데, 그 목적이 있다.The present invention relates to a method for producing zirconia (ZrO 2 ) from zircon (ZrSiO 4 ) sand, the manufacturing process is simpler and more economical than the conventional method, and a method for producing zirconia using heat plasma that does not generate environmental pollutants To provide, the purpose is.
본 발명은 탄소/지르콘샌드의 몰비가 1.0이상이 되도록 지르콘샌드에 탄소를 첨가하여 혼합하는 단계 ; 상기와 같이 혼합된 혼합물을 단광으로 제조하는 단계 ; 상기 단광을 고온의 열프라즈마에 의해 가열용융한 후 냉각하고 이때 생성된 고체 생성물을 회수, 분쇄하는 단계를 포함하여 지르콘샌드로부터 지르코니아를 제조하는 방법을 그 요지로 한다.The present invention comprises the steps of mixing by adding carbon to the zircon sand so that the molar ratio of carbon / zircon sand is 1.0 or more; Preparing the mixed mixture as briquettes as described above; The subject matter is a method for producing zirconia from zircon sand, including the step of melting the briquettes by hot melting plasma and then cooling and recovering and pulverizing the resulting solid product.
