Claims (8)

고주파 유도 코일내에 구리관의 외주면을 석고로 피복한 스컬 용기에 지르코늄디옥사이드 분말과 이트륨옥사이드 분말을 균일하게 혼합한 원료를 스컬 용기 내부 높이의 1/2이 되도록 층진시키고 이를 고주파 유도 코일의 저면으로 부터 하향 이격되게 설치하고 가열하여 원료가 완전 용융된 후 3단계에 걸쳐 스컬 용기를 고주파 유도 코일로 부터 이탈시킨 다음, 가열을 중지하고 구리관의 내부에 냉각수를 순환시켜 성장된 단결정을 상온으로 냉각시킴을 특징으로 하는 큐빅지르코니아의 단결정 제조방법.In the high frequency induction coil, the outer surface of the copper tube is coated with gypsum on a skull container, and the raw material, which is a mixture of zirconium dioxide powder and yttrium oxide powder, is layered to be 1/2 of the height inside the skull container, and is then layered from the bottom of the high frequency induction coil. After the raw material is completely melted and installed downwardly, the skull container is separated from the high frequency induction coil in three stages after the raw material is completely melted.Then, the heating is stopped and the coolant is circulated inside the copper pipe to cool the grown single crystal to room temperature. Method for producing a single crystal of cubic zirconia, characterized in that. 제1항에 있어서, 스컬 용기는 고주파 유도 코일의 저면으로 부터 스컬 용기 외경의 0.3배 길이 만큼 하향 이격되게 설치함을 특징으로 하는 제조방법.The method of claim 1, wherein the skull container is installed from the bottom of the high frequency induction coil spaced apart by 0.3 times the length of the outer diameter of the skull container. 제1항에 있어서, 지르코늄디옥사이드 분말과 이트륨옥사이드 분말의 혼합비를 mol%로 91 : 9(wt%로 85 : 15)의 비율임을 특징으로 하는 제조방법.The method of claim 1, wherein the mixing ratio of the zirconium dioxide powder and the yttrium oxide powder in mol% is 91: 9 (wt% 85: 15) ratio. 제1항에 있어서, 스컬용기를 원료가 완전히 용융된 후 1단계에서는 시간당 1-2mm의 속도로 2-5시간, 2단계에서는 시간당 10-20mm의 속도가 되도록 2-4시간 점증시킨 다음, 3단계에서는 시간당 10-20mm의 속도를 유지시키면서 하강시킴을 특징으로 하는 방법.The method of claim 1, wherein after the raw material is completely melted, the scull container is increased 2-5 hours at a speed of 1-2mm per hour in the first step, 10-4mm per hour in the second step, and then 3 Step down while maintaining a speed of 10-20mm per hour. 제1항에 있어서, 원료를 충진함에 있어서 직경 2-4mm의 알갱이나 다공질의 스폰지 형태의 지로코늄 또는 이트륨금속을 충진된 원료로 중앙부에 두도록함을 특징으로 하는 방법.The method of claim 1, wherein the filling of the raw material is made of granulated or porous sponge-like zirconia or yttrium metal in the center of the raw material. 제1항에 있어서, 원료가 완전히 용융된 후에 1-2시간 추가로 유도 가열함을 특징으로 하는 방법.The method of claim 1, wherein the induction heating is further performed for 1-2 hours after the raw material is completely melted. 제1항에 있어서, 성장된 단결정을 1400-1500℃의 온도에서 추가로 열처리함을 특징으로 하는 방법.The method of claim 1, wherein the grown single crystal is further heat treated at a temperature of 1400-1500 ° C. 제1항에 있어서, 원료가 용융될시 연속적으로 원료를 보충하여 스컬 용기를 채움을 특징으로 하는 방법.The method of claim 1 wherein the raw material is melted to continuously replenish the raw material to fill the skull container. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
