본 발명의 S1단계에 있어서, 슬래그는 쓰레기 용융 슬래그, 하수 슬러지 용융 슬래그, 금속 제련시 생성되는 유리질 슬래그(예를 들면 고로슬래그, 제강슬래그, 전로슬래그, 전기로 슬래그 등의 철강 슬래그), 무정형 유기물이 봉인된 석탄재로 이루어지는 군 중에서 선택된 적어도 1종인 것을 예시할 수 있다.In step S1 of the present invention, the slag is waste molten slag, sewage sludge molten slag, glassy slag generated during metal smelting (for example, blast furnace slag, steelmaking slag, converter slag, steel slag such as electric furnace slag), amorphous organic matter At least one selected from the group consisting of the sealed coal ash can be exemplified.
상기 슬래그에는 0.5mm 내지 0.15mm인 유리질 슬래그를 10~50중량% 함유할 수 있는데, 유리질 슬래그의 입경이 0.5㎜ 이상이 되면 가열시 골격 입자 사이의 관통 간극이 커지기 때문에 성형체의 형상을 유지하기 어렵게 되고, 0.15㎜ 이하의 함유량이 10 중량% 이하로 떨어질 경우 골격 입자 사이의 관통 간극이 줄어들어 대형 세라믹 패널의 투수 성능이 저하하기 쉬워진다.The slag may contain 10 to 50% by weight of vitreous slag of 0.5 mm to 0.15 mm. If the particle diameter of the vitreous slag is 0.5 mm or more, the penetration gap between the skeletal particles increases during heating, making it difficult to maintain the shape of the molded body. When the content of 0.15 mm or less falls to 10 wt% or less, the penetration gap between the skeletal particles is reduced, so that the water permeability of the large-sized ceramic panel is easily deteriorated.
