Abstract

본 발명은 알루미늄 나이트레이트 용액 및 마그네슘 나이트레이트 용액을 혼합하는 단계와, 혼합 용액에 실리카 화합물의 졸을 첨가하여 균일하게 혼합하는 단계와, 얻어진 혼합물에 보강재의 분산액을 첨가하고 균일하게 혼합하는 단계와, 생성된 혼합물을 겔화하여 건조시킨 후 300 내지 500℃에서 하소한 다음 분쇄하여 코디에라이트 분말을 제조하는 단계를 포함하는 코디에라이트 기지의 세라믹 복합체의 제조방법에 관한 것으로, 본 발명의 방법에 따라서 코디에라이트 제조시와 복합체 제조시 중복되는 교반과정 및 건조과정을 단일화함으로써 작업시간과 비용을 절감할 수 있고 공정을 단순화함으로서 회분식 작업에 의한 대량생산이 가능한 이점이 있다.
