Abstract

본 발명은 스크랩(scrap), 칩(chip), 와이어(wire), 스폰지(sponge)형태의 지르코늄 원료를 이용하여 분말을 제조하는 지르코늄 분말 제조 방법에 관한 것이다.The present invention relates to a zirconium powder production method for producing a powder using a zirconium raw material in the form of scrap, chip, wire, sponge.

본 발명은 지르코늄 원료 자체에서 생성된 반응열에 의하여 자발적으로 화학반응을 일으키게 하여 지르코늄 수소화물을 형성하고, 이를 분쇄한 분말을 진공가열시켜 지르코늄 분말을 제조하는 것으로, 생산공정이 아주 간단하고, 에너지 소모가 아주 적고, 제조시간이 아주 짧은 장점이 있다. 따라서 지르코늄 분말을 저렴한 가격으로 다량으로 제조할 수 있어 그 적용 범위를 극대화할 수 있는 효과가 있다.The present invention is to produce a zirconium hydride by spontaneously causing a chemical reaction by the reaction heat generated from the zirconium raw material itself, and to produce a zirconium powder by vacuum heating the pulverized powder, the production process is very simple, energy consumption Is very small and the manufacturing time is very short. Therefore, the zirconium powder can be manufactured in large quantities at a low price, thereby maximizing its application range.
