HIGH-STRENGTH LOW TEMPERATURE CO-FIRED CERAMIC COMPOSITION
The present invention provides a high-strength low-temperature co-fired ceramic composition which has excellent thermal conductivity. The high-strength low-temperature co-fired ceramic composition may include anorthite-based glass (CaO·Al_2·O_3·2SiO_2), diopside-based crystalline phase (CaO·MgO·2SiO_2) and alumina (Al_2O_3). Specifically, in the ceramic composition according to the present invention, anorthite phase, diopside phase and alumina phase may coexist after firing is performed at a low temperature of 900°C or less by using a thick film process. Preferably, a high-strength low-temperature co-fired ceramic composition may include 30-70 wt% of anorthite-based glass, 10-40 wt% of diopside-based crystalline phase and 10-40 wt% of Al_2O_3.
본 발명의 세라믹스 조성물은 아노사이트계 글라스(CaO·AlO·2SiO)와 디옵사이드계 결정상(CaO·MgO·2SiO) 및 알루미나(AlO)를 포함한 조성으로 될 수 있다. 특히, 본 발명의 상기 세라믹스 조성물은 후막공정을 이용하여 저온인 900℃ 이하의 소성 후 아노사이트 상, 디옵사이드 상, 알루미나 상 및 글라스 상이 공존할 수 있고, 바람직하게는 30~70wt%의 아노사이트계 글라스와 10~40wt%의 디옵사이드계 결정상 및 10~40wt%의 AlO를 포함한 조성으로 될 수 있다.
