Title (EN) ZIRCONIA SINTERED BODY USING REDUCTION FIRING, AND METHOD FOR PRODUCING SAME
(FR) CORPS FRITTÉ EN ZIRCONE UTILISANT UNE CUISSON RÉDUCTRICE ET SON PROCÉDÉ DE PRODUCTION
(KO) 환원소성을 이용한 지르코니아 소결체 및 그 제조방법
Abstract: front page image
(EN)The present invention is characterized by a zirconia sintered body and a method for producing a sintered body, wherein the method comprises: a molding step for forming a zirconia molded body that has zirconia as a main component and includes a redox oxide; and a zirconia reduction firing step in which the color of the zirconia molded body is changed by means of including a reduction metal oxide therein by adjusting at least one selected from among the firing temperature, the firing time, and the reduction firing gas partial pressure in a reduction firing atmosphere for supplying a reduction firing gas to a firing furnace.
(FR)La présente invention est caractérisée par un corps fritté en zircone et un procédé de production d'un corps fritté, le procédé comprenant : une étape de moulage pour former un corps moulé en zircone qui comporte de la zircone en tant que composant principal et comprend un oxyde redox; et une étape de cuisson réductrice de zircone dans laquelle la couleur du corps moulé en zircone est modifiée au moyen de l'inclusion d'un oxyde métallique de réduction dans celui-ci par ajustement d'au moins un élément choisi parmi la température de cuisson, le temps de cuisson, et la pression partielle de gaz de cuisson réductrice dans une atmosphère de cuisson réductrice pour distribuer un gaz de cuisson réductrice dans un four de cuisson.
(KO)본 발명은 지르코니아를 주성분으로 하며, 레독스산화물을 포함하는 지르코니아 성형체를 형성하는 성형단계 및 환원소성가스를 소성로에 공급하는 환원소성 분위기에서 소성온도, 소성시간 및 환원소성가스 분압 중 선택되는 적어도 하나를 조절하여 환원금속산화물을 포함하는 방식으로 지르코니아 성형체의 색상을 변화시키는 지르코니아 환원소성단계를 포함하는 지르코니아 소결체 및 소결체 제조 방법을 특징으로 한다.
