Abstract
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 'T' (° C.) and the softening point of the second organic component is defined as 'T' (° C.), the kneading step is carried out at a temperature in the range of Tor higher but lower than Tafter the raw powder and the organic binder are preheated at a temperature in the range of Tto T+100(° C.). An orthodontic member is also provided.
