COMPOSITE REFRACTORY AND METHOD FOR MANUFACTURING THE SAME
The present invention provides a technology capable of obtaining a setter having excellent thermal shock resistance. A composite refractory material contains 35-70 wt% of SiC and 25-60 wt% of metal Si as a chemical composition, and is formed with a first Si-SiC sintered compact part (1) having a fibrous three-dimensional structure and a second Si-SiC sintered compact part (2) which is a matrix for supporting the fibrous three-dimensional structure, wherein the first Si-SiC sintered compact part (1) is covered with the second Si-SiC sintered compact part (2), and the first Si-SiC sintered compact part (1) and the second Si-SiC sintered compact part (2) both are formed of a dense substance having 1% of porosity or less.
(과제) 내열충격성이 우수한 세터를 얻을 수 있는 기술을 제공하는 것. (해결 수단) 화학 성분으로서, SiC를 35∼70 질량%만큼, 그리고 금속 Si를 25∼60 질량%만큼 함유하고, 섬유형의 3차원 구조를 갖는 제1 Si-SiC 소결체부(1)와, 상기한 섬유형의 3차원 구조를 지지하는 매트릭스인 제2 Si-SiC 소결체부(2)로 구성되고, 상기 제1 Si-SiC 소결체부(1)를 제2 Si-SiC 소결체부(2)로 덮은 구조를 갖고 있으며, 상기 제1 Si-SiC 소결체부와 제2 Si-SiC 소결체부는 모두 기공률 1% 이하의 치밀질로 이루어진다.
