AGGREGATE FOR REFRACTORY, MANUFACTURING METHOD THEREFOR AND REFRACTORY USING THE SAME
PROBLEM TO BE SOLVED: To provide an aggregate for refractory which is less in sinter shrinkage even when used at a high temperature, has CaO 6AlO(CA6) as a crystal phase suppressing detachment or collapse, is porous and has adiabaticity.SOLUTION: There is provided a CA6 particle for refractory having bulk density of 0.6 g/cm3 when screened to particle diameter of 3 to less than 6 mm, and cumulative volume of particle diameter of 20 μm or less of 30% or less in a particle size measurement by a laser scattering type particle diameter distribution measurement device when screened to particle diameter of less than 1 mm.SELECTED DRAWING: Figure 1
【課題】高温での使用でも焼結収縮が少なく、剥離や崩壊を抑制するＣａＯ・６Ａｌ２Ｏ３（ＣＡ６）を結晶相とする多孔質で断熱性を有する耐火物用骨材の提供。【解決手段】粒径３〜６ｍｍ未満に篩分けしたときの嵩密度が０．６ｇ／ｃｍ３以下であり、粒径１ｍｍ未満に篩分けしたときの、レーザー散乱式粒子径分布測定装置による粒度測定において粒径２０μｍ以下の体積累計が３０％以下である耐火物用ＣＡ６粒子。【選択図】図１
