Method of manufacturing translucent ceramic and orthodontic member |
摘要 |
A method of manufacturing a translucent ceramic is provided. The method comprises: mixing a raw powder and an organic binder and kneading them to obtain a compound, the raw powder containing an aluminum oxide powder and a magnesium oxide powder, and the organic binder containing a first organic component and a second organic component; molding the compound in a predetermined shape by an injection molding method to obtain a green body; debinding the organic binder contained in the green body to obtain a brown body; and sintering the brown body to obtain a sintered body of the translucent ceramic. When the softening point of the first organic component is defined as T1 (° C.) and the softening point of the second organic component is defined as T2 (° C.), the kneading step is carried out at a temperature in the range of T2 or higher but lower than T1 after the raw powder and the organic binder are preheated at a temperature in the range of T1 to T1+100(° C.). An orthodontic member is also provided. |
