Abstract

본 발명은 도가니에 망간-아연 페라이트용액을 장입하여 발열부가 설치된 성장로 내의 노심관 사이를 수직 또는 강하시킨 다음 일정 온도로 서냉하여 페라이트 단결정을 성장시키는 연속공급식 브리지맨방식의 페라이트 단결정 성장장치에 있어서, 페라이트 단결정의 조성을 일정하게 성장시키기 위한 추가원료의 공급수단으로 일정 간격으로 홈이 형성된 회전체와 과립형태의 추가원료가 저장되는 원료저장용기와 투입되는 과립원료의 주도가니로의 전달통로인 깔대기로 구성되는 과립투입기를 주도가니 위에 설치하여, 과립투입기를 통해 과립상태의 추가원료를 일정한 양으로 성장되는 주도가니의 초기원료에 연속적으로 투입되도록 함으로써, 보조도가니의 사용에 따른 백금 혼입의 불량을 줄이고 단결정 성장의 제조원가를 절감시키며 성장작업의 안정성으로 보다 대형의 단결정 제조를 가능하게 한 망간-아연 페라이트 단결정 성장장치에 관한 것이다.In the present invention, a manganese-zinc ferrite solution is charged to a crucible, and the ferrite single crystal growth apparatus of a continuous feeding bridgeman method for growing ferrite single crystals by vertically or lowering the core tube in a growth furnace in which a heating part is installed and then slowly cooling to a predetermined temperature. In the present invention, a feed passage of a raw material storage container in which grooves are formed at regular intervals and a raw material storage container for storing additional materials in a granular form and a granule material introduced into the main crucible as a means for supplying additional raw materials for constantly growing the composition of the ferrite single crystal The granulation injector composed of the funnel is installed on the main crucible, and the additional raw material in the granular state is continuously introduced into the initial raw material of the growing crucible by a certain amount through the granulation injector. To reduce the manufacturing cost of single crystal growth It relates to a manganese-zinc ferrite single crystal growth apparatus that enables the production of larger single crystals with the stability of the up.

Claims

In a ferrite single crystal growth apparatus of a continuous feeding bridgeman method in which a manganese-zinc ferrite solution is charged to a main crucible and vertically or lowered between core tubes in a growth furnace in which a heating unit is installed, and then slowly cooled to a certain temperature to grow ferrite single crystal. The manganese-zinc ferrite initial raw material is inserted into the groove at the peripheral edge of the main crucible loaded with a predetermined interval to rotate the rotating body at a constant speed, and granular ferrite additional raw material to be easily supplied into the groove of the rotating body A granule storage container forming a bell-shaped spout in the lower part and a granulator feeding device composed of a funnel for easily adding ferrite additional raw materials of the granule storage container into the main crucible through the rotating body to constantly grow the composition of the ferrite single crystal. As a means of supplying additional raw materials, Manganese-zinc ferrite single crystal growth apparatus characterized in that the installation.
