Conductive Titanium Dioxide Sintered Body And Its Manufacturing Method Using Pressure Casting Molding Method
The present invention relates to a conductive titanium dioxide sintered body and a manufacturing method thereof. According to the present invention, after mixing an anatase-phase titanium dioxide powder and rutile-phase titanium dioxide powder in an optimal ratio and molding a mixture by a pressure casting molding method, a conductive titanium dioxide sintered body is manufactured under optimal sintering conditions and heat treatment conditions. Accordingly, the conductive titanium dioxide sintered body has the relative sintered density of 97 to 97.5 % compared to the theoretical density of rutile phase titanium dioxide, which is a high-temperature stable phase. In addition, the conductive titanium dioxide sintered body has no strength loss due to optimized pore formation even though an average particle size of titanium dioxide sufficiently grows to 20 ㎛ by sintering, and has a low volume resistance of 0.9 to 1.1 Ω•cm. Therefore, a component for manufacturing a conductive semiconductor having no risk of generating static electricity can be manufactured.
본 발명 도전성 이산화티타늄 소결체 및 이의 제조방법은 아나타제상 이산화티타늄 분말과 루타일상 이산화티타늄 분말을 최적의 비율로 혼합하고 이를 가압 캐스팅 성형법으로 성형한 후 최적의 소결조건 및 열처리 조건으로 도전성 이산화티타늄 소결체를 제조하므로 고온 안정상인 루타일상 이산화티타늄의 이론밀도 대비 97내지 97.5%의 상대소결밀도를 가지며 소결로 인해 이산화티타늄의 평균입자크기가 20㎛으로 충분히 성장하였음에도 기공 형성이 최적화되어 강도 저하가 없고 0.9 내지 1.1 Ω·㎝의 낮은 체적저항을 가져 정전기 발생 우려가 없는 도전성 반도체 제조용 부품을 제조할 수 있는 장점이 있다.
