Claims (5)
- 원료용해부, 용액공급부와 결정성장부로 구성되는 Pt-Rh도가니, 원료 용해부와 용액공급부의 정밀한 온도 제어를 위한 발열체, 용액공급부의 용융 온도 조절에서 원료 용해부 온도의 영향을 최대한 배제시키기 위한 세라믹재 열적 배플(theratl baffle), 종결정이 장착되도록 설치한 플링로드(pulling rod), 결정인발이 시작되기 전에 종결정이 용융되는 것을 방지하기 위한 물재킷(water jacket)으로 구성됨을 특징으로 하는 망간-아연 페라이트 단결정의성장장치.
- 제1항에 있어서, Pt-Rh도가니의 원료용융부와 용액공급부의 온도가 독립된 발열제에 의해 각각 제어되는 것임을 특징으로 하는 망간-아연 페라이트 단결정의 성장장지.
- 제1항에 있어서, Pt-Rh도가니의 용액공급부는 길이 10cm이내, 직경이 2∼3mm인 봉상의 모세관 임을 특징으로 하는 망간-아연 페라이트 단결정의 성장장치.
- 제1항에 있어서, Pt-Rh도가니의 결정성장부의 액막이 도가니벽과 분리된 상태로 응고되는 것임을 특징으로 하는 망간-아연 페라이트 단결정의 성장장지.
- 제1항 내지 제4항중 어느한항의 방법으로 망간-아연 페라이트 단결정을 성장시키되 제어된 조성의 망간-아연 소결체를 Pt-Rh도가니의 상부에 연속적으로 투입하고, 용융이 이루어진 용액을 Pt-Rh모세관을 따라 하단 인발부로 연속 공급하여 액막을 형성시킴을 특징으로 하는 망간-아연 페라이트 단결정의 제조방법 .
