METHOD FOR DEGREASING CERAMIC COMPACT AND PROCESS FOR PREPARING CERAMIC SINTERED BODY
PROBLEM TO BE SOLVED: To provide a method for degreasing ceramic compact in which the time required until the completion of degreasing is sufficiently shortened as compared to the conventional methods.SOLUTION: The method includes degreasing a ceramic compact having a predetermined shape obtained by forming a slurry containing a ceramic powder, an organic binder and a dispersion medium, by heat treating in a superheated steam containing an oxygen gas having a logarithmic value of oxygen gas partial pressure PO(atm) in a range of -2 to -0.66, at 600 to 1000°C.SELECTED DRAWING: None
【課題】従来に比べて脱脂が完了するまでに要する時間を十分短くする。【解決手段】セラミック粉末、有機バインダ及び分散媒を含むスラリーを成形して得られる所定の形状のセラミック成形体を、酸素ガス分圧ＰＯ2（ａｔｍ）の対数値が−２〜−０．６６の範囲となる酸素ガスを含む過熱水蒸気中、６００〜１０００℃で熱処理することで脱脂する。【選択図】なし
