Abstract

본 발명은 세라믹스의 단점인 깨지기 쉬운(Brittle) 특성을 개선하기 위해 높은 파괴 인성치를 갖는 세라믹스를 제조하고자 하는 것이며 이같은 목적을 달성하고자 세라믹스 내부에 물라이트의 침상 결정상 란타니움 베타 알루미나의 침상결정상 및 지르코니아상 등이 혼재되도록 한 것이다.The present invention is to manufacture a ceramic having a high fracture toughness in order to improve the brittle characteristics, which is a disadvantage of ceramics. The images are mixed.

이같은 상들이 효과적으로 생성되게 하기 위해서는 원료 각 성분 및 함량 그리고 원료의 입도가 매우 중요하다.In order to produce these phases effectively, each ingredient and content of the raw material and the particle size of the raw material are very important.

본 발명으로 제조한 세라믹스는 알루미나에 비해 높은 파괴인성치를 갖으며 열팽창 계수가 작아서 기계부품이나 고온구조재용 및 내마모성 부품이나 비드제품 등에 응용될 수 있다.Ceramics prepared by the present invention have a higher fracture toughness than alumina and have a low coefficient of thermal expansion, and thus may be applied to mechanical parts, high temperature structural materials, wear resistant parts, and bead products.
