GRANULAR POWDER FOR FORMING GLASS CERAMIC SINTERED BODY, GLASS CERAMIC TEMPORARILY SINTERED BODY AND METHOD FOR PRODUCING THE SAME
PROBLEM TO BE SOLVED: To prevent the occurrence of large voids when forming a glass ceramic sintered body by sintering a glass ceramic temporarily sintered body made using granular powder for forming a glass ceramic sintered body comprising glass powder, ceramic powder and binder resin.SOLUTION: The present invention provides granular powder for forming a glass ceramic sintered body, comprising glass powder, ceramic powder and binder resin, having a granular size on a sieve with an opening of 45 μm, and a ratio of bulk specific density/absolute specific gravity of 0.2 or more.SELECTED DRAWING: Figure 1
【課題】ガラス粉末とセラミック粉末とバインダー樹脂とを含むガラスセラミック焼結体形成用顆粒粉末を用いて作製したガラスセラミック仮焼結体を焼成してガラスセラミック焼結体を形成する際、大きなボイドの発生を抑制する。【解決手段】ガラス粉末とセラミック粉末とバインダー樹脂とを含むガラスセラミック焼結体形成用顆粒粉末であって、目開き４５μｍの篩上の粒度を有し、嵩比重／真比重の比率が０．２以上であることを特徴としている。【選択図】図１
