BEDDING POWDER AND PRODUCTION METHOD OF BEDDING POWDER
To provide a bedding powder which the degree of metal penetration is more improved than the conventionally used bedding powder, when the material to be fired is fired.MEANS: A bedding powder of this invention comprises AlOof 70 wt% to 91 wt%, MgO of 8 wt% to 30 wt%, and at least a portion of the AlOforms a spinel structure (MgO.AlO) with at least a portion of MgO, and the total amount of the wt% of AlOand the wt% of MgO is 98.0 wt% to 100 wt%.SELECTED DRAWING: None
【課題】焼成物の焼成にあたり従来使用されてきた敷粉よりも焼着の程度が改善された敷粉を提供する。【手段】敷粉は、７０重量％以上９１重量％以下のＡｌ２Ｏ３と、８重量％以上３０重量％以下のＭｇＯとを含み、前記Ａｌ２Ｏ３の少なくとも一部と前記ＭｇＯの少なくとも一部とがスピネル（ＭｇＯ・Ａｌ２Ｏ３）を形成しており、前記Ａｌ２Ｏ３の重量％と前記ＭｇＯの重量％との合計が９８．０重量％以上１００重量％以下であることを特徴とする。【選択図】なし
