Abstract:
(EN) The present invention relates to a method for manufacturing Y-type ferrite, and to Y-type ferrite manufactured by same. The method for manufacturing Y-type ferrite according to the present invention comprises a heat treatment step performed at least once, wherein said heat treatment step includes a primary heat treatment step performed at a temperature of 300°C to 500°C, and a secondary heat treatment step performed at a temperature of 1100°C to 1250°C. The method of the present invention is capable of manufacturing Y-type ferrite with a low permittivity, a high magnetic permeability, a low dielectric loss, and a low permeation loss, simply by controlling the heat treatment temperature without substituting a portion of initial materials or without using any additives. Therefore, the Y-type ferrite of the present invention can be used as an element for high frequency (3GHz or lower) devices, and processes for manufacturing the Y-type ferrite can be simplified, and the costs of manufacturing Y-type ferrite can be reduced.
(FR) La présente invention concerne un procédé de fabrication de ferrite de type Y et une ferrite de type Y ainsi fabriquée. Le procédé de fabrication de ferrite de type Y d'après la présente invention comprend une étape de traitement thermique mise en œuvre au moins une fois, ladite étape de traitement thermique comprenant une étape de traitement thermique primaire mise en œuvre à une température de 300 °C à 500 °C et une étape de traitement thermique secondaire mise en œuvre à une température de 1100 °C à 1250 °C. Le procédé de la présente invention permet de fabriquer une ferrite de type Y ayant une permittivité basse, une perméabilité magnétique élevée, une faible perte diélectrique et une faible perte de perméation simplement en régulant la température du traitement thermique, sans remplacer une partie des matériaux initiaux ni utiliser d'additif. Par conséquent, la ferrite de type Y de la présente invention s'utilise comme un élément destiné à des dispositifs à haute fréquence (3 GHz ou moins), les procédés de fabrication de la ferrite de type Y peuvent être simplifiés et les coûts de fabrication de la ferrite de type Y peuvent être réduits.
(KO) 본 발명은 와이 타입 페라이트 제조 방법 및 이에 의해 제조된 와이 타입 페라이트에 관한 것이다. 본 발명에 따른 와이 타입 페라이트 제조방법은 일 회 이상 열처리하는 열처리 단계를 포함하며, 상기 열처리단계는 300℃ 내지 500℃에서 제 1차 열처리를 수행하는 단계 및 1100℃ 내지 1250℃에서 제 2차 열처리를 수행하는 단계를 포함한다. 본 발명에 의하면, 초기 원료의 일부를 치환하거나 첨가물을 추가하지 않고 열처리 온도만을 조절하여 낮은 유전율과 높은 투자율, 낮은 유전 손실과 낮은 투자손실 값을 가지는 와이 타입 페라이트를 제조할 수 있다. 따라서 고주파(3GHz 이하)용 소자로 적용이 가능하고, 와이 타입 페라이트의 제조 공정이 간단해질 뿐만 아니라 와이 타입 페라이트의 제조 비용을 절감할 수 있는 효과가 있다.
