METHOD OF MANUFACTURING TRANSLUCENT CERAMIC AND ORTHODONTIC MEMBER |
摘要 |
<p>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 1 " (°C) and the softening point of the second organic component is defined as "T 2 " (°C), the kneading step is carried out at a temperature in the range of T 2 or higher but lower than T 1 after the raw powder and the organic binder are preheated at a temperature in the range of T 1 to T 1 +100 (°C). An orthodontic member is also provided.</p> |
