Abstract

본 발명은 Al2O3를 주성분으로 하는 전자부품용 착색 알루미나 세라믹 조성물에 관한 것으로, 좀 더 구체적으로는 알루미나를 기본으로 하는 산화물 95.5~98.7wt%와 착색조제로 Cr2O31~3wt%, Tio20.2~0.8wt%, Nb2O50.1~0.7wt%를 첨가시킨 전자부품용 암색계 착색 알루미나 절연체 자기 조성물에 관한 것이다.The present invention relates to a colored alumina ceramic composition for an electronic component having Al 2 O 3 as a main component. More specifically, 95.5 to 98.7 wt% of an oxide based on alumina and 1 to 3 wt% of Cr 2 O 3 as a coloring aid. The present invention relates to a dark colored colored alumina insulator porcelain composition for an electronic component comprising 0.2 to 0.8 wt% of Tio 2 and 0.1 to 0.7 wt% of Nb 2 O 5 .

Cr2O3, Tio2, Nb2O5의 착색제를 동시에 사용함으로서 환원 분위기중, 소성온도 1500~1650℃에서 소성 가능하며 흑색으로 착색될 뿐만 아니라 절연지항이 5Ω㎝이상이고, 유전 상수가 9~10이며, 유전손실이 1×10-3이하인 착색알루미나 세라믹 조성물을 얻을 수 있었다.By using Cr 2 O 3 , Tio 2 , Nb 2 O 5 simultaneously, it can be fired at reducing temperature 1500 ~ 1650 ℃ in reducing atmosphere and colored black and insulation area is 5 착색 ㎝ and dielectric constant is 9 ~ 10, a colored alumina ceramic composition having a dielectric loss of 1 × 10 −3 or less was obtained.
