Pyrolytic Boron Nitride
PBN 열분해 질화 붕소
PBN은 순도 99.999%의 육방정계 첨단세라믹 재료로서 내산성, 화학적 비활성, 열전도성, 가공성 등에서 우수한 특성을 보입니다.
고온 · 고진공 상태에서 암모니아와 붕소의 할로겐화합물을 이용한 화학적 기상 증착법(CVD 공법)을 통해 생산되며, Crucible, Boat, Ring, Plate 등의 형상 가공 뿐 아니라 특정 제품의 표면 보호 코팅용으로 적용하기도 합니다.
*해당 페이지에는 전체 제품 중 일부 규격에 한해 기재되어 있습니다. 기재되어 있지 않은 규격의 제품도 맞춤 공급 가능합니다.
