Beschreibung
Zusammenfassung:	A method for manufacturing a chalcogenide ingot is provided. The method includes the steps of: purifying Ge; weighing purified Ge, Sb, and Se; melting and synthesizing a mixture of Ge, Sb, and Se; and annealing a composite. The melting and synthesizing step is performed in a locking furnace through multi-step heating. An ingot manufactured in this way can be cut into a preform and can be manufactured into an infrared optical lens through molding. 칼코케나이드 잉곳을 제조하는 방법이 제공된다. 이는 Ge을 정제하는 단계와, 정제된 Ge, Sb, 및 Se를 칭량하는 단계와, Ge, Sb, 및 Se의 혼합물을 용융하여 합성하는 단계와, 합성물을 어닐링하는 단계를 포함한다. 용융하여 합성하는 단계는 락킹로에서 수행하며, 다단계의 가열을 통해 수행한다. 이렇게 제조된 잉곳은 프리폼으로 컷팅되어 몰딩 성형을 통해 적외선 광학 렌즈로 제조될 수 있다.
