CERAMIC TRAY, AND HEAT TREATMENT METHOD AND HEAT TREATMENT DEVICE USING THE SAME
To provide a ceramic tray which can suppress influence of a step surface on a treatment body, and a heat treatment method using the ceramic tray.SOLUTION: A ceramic tray includes a plurality of through holes having a large diameter part and a small diameter part along a thickness direction. A step surface present between the large diameter part and the small diameter part represents a difference between a cut level in a load length ratio of 25% in a roughness curve of the step surface and a cut level in a load length ratio of 75% in the roughness curve. The cut level difference (Rδc) in the roughness curve is 4 μm or less.SELECTED DRAWING: Figure 3
【課題】被処理体に対する段差面の影響を抑制することができるセラミックトレイおよびこれを用いる熱処理方法を提供する。【解決手段】厚さ方向に沿って大径部と小径部とを有する複数の貫通孔を備え、大径部と小径部との間に存在する段差面は、該段差面は、該内周面の粗さ曲線における２５％の負荷長さ率での切断レベルと、前記粗さ曲線における７５％の負荷長さ率での切断レベルとの差を表す、前記粗さ曲線における切断レベル差（Ｒδｃ）が４μｍ以下である。【選択図】図３
