Claims (9)

  1. 순도가 최소한 99.97중량% 이상인 몰리브덴을 갖는, 램프 제조용, 몰리브덴 재료에 있어서, 알루미늄이 단일 도핑제로서 존재함을 특징으로 하는 몰리브덴 재료.
  2. 제1항에 있어서, 알루미늄 함량이 150 내지 800중량 ppm인 몰리브덴 재료.
  3. 제1항에 있어서, 알루미늄 함량이 400 내지 600중량 ppm인 몰리브덴 재료.
  4. 제1항 내지 3항중 어느 한항에 있어서, 몰리브덴 재료를, 이외에 소량의 칼륨과 도핑하는 몰리브덴 재료.
  5. 제4항에 있어서, 칼륨 함량이 5 내지 50중량 ppm인 몰리브덴 재료.
  6. 알루미늄을, 차후에 환원되는 불안정한 화합물, 특히 질산염으로서, 세립화된 몰리브덴 화합물에 첨가하는 제1항 몰리브덴 재료의 제조방법.
  7. 제6항에 있어서, 몰리브덴 화합물이 99.97중량%보다 큰 순도를 갖는 MoO₃인 몰리브덴 재료의 제조방법.
  8. 제6항에 있어서, 환원된 몰리브덴을 로드형으로 압착하고, 이 로드를 통하여 전기적 흐름이 없는 약 1700℃의 온도에서 차후에 소결하는 제조방법.
  9. 제8항에 있어서 도핑한 몰리브덴의 소결한 로드를 차후에 튜브, 만드렐선 또는 지지선으로 처리하는 방법.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
