Abstract
본 발명은 브릿지만법을 이용한 망간-아연 페라이트 연속공급식 단결정 성장시 추가적으로 원료를 공급하는 경우 값비싼 백금 보조도가니를 사용치 않으며 분말상태의 원료를 투입시킴에 따라 원료처리공정이 단순화되며 단결정 성장시 백금 및 불순물의 혼입을 차단시켜 특성이 우수한 단결정을 성장시킬 수 있는 망간-아연 페라이트 단결정 성장시 원료공급장치에 관한 것으로, 브릿지만법에 의한 연속공급식 망간-아연 페라이트 단결정 성장시 추가적으로 원료를 공급함에 있어서, 진동자에 연결된 원료공급호스 하단부에 이를 포함하는 외부전원부와 연결된 코일이 설치되고, 상기 원료공급호스로부터 공급되는 분말상태의 원료가 코일내부를 통과하면서 집적되고 발열체부에 의해 용융되어 주도가니에 낙하되는 액적을 감지하는 센서가 발열체부의 하방에 설치된 것인것이다.The present invention does not use expensive platinum auxiliary crucibles when additional raw materials are supplied during the manganese-zinc ferrite continuous feeding single crystal growth using the Bridgeman method. The present invention relates to a raw material supply device for growing manganese-zinc ferrite single crystals that can block the incorporation of platinum and impurities in the growth of single crystals with excellent characteristics. In the supply, a coil connected to an external power source including the same is installed at the lower end of the raw material supply hose connected to the vibrator, and powdered raw material supplied from the raw material supply hose is integrated while passing through the coil and melted by the heating element. Sensor to detect droplets falling into the crucible Of which it will be provided below.
