| titleOfInvention | Method of manufacturing green ZrO2 sintered body |
| abstract | The present invention relates to a method for producing a ZrO 2 sintered body having a variety of bright green to dark green colors.n n n Conventionally, a method of manufacturing a green ZrO 2 sintered body has a problem in that it is impossible to mass-produce ZrO 2 ceramics so that reproducibility can be achieved without deviation between the specimens, .n n n The green ZrO 2 sintered body according to the present invention is manufactured by heat-treating the green ZrO 2 sintered body at 900 to 1300 ° C for 1 to 4 hours in an oxidizing atmosphere, then subjecting ZrO 2 to 87 to 94.7% by weight and Y 2 O 3 to 5 to 6% And then sintered in an oxide furnace at 1300 to 1600 ° C for 1 to 4 hours. The sintered body is then sintered at 1200 to 1550 ° C under an argon pressure of 500 to 1000 bar for 0.5 to 2 hours Lt; / RTI >n n n The green ZrO 2 sintered body manufactured according to the present invention has high transparency and can mass produce ZrO 2 sintered body having various green colors ranging from light green to dark green depending on the temperature during HIP and oxidation heat treatment without deviation between specimens. In addition, it is possible to mass-produce sophisticated dark green ZrO 2 sintered bodies with good transparency that can be applied to high value added ornaments. |
