PROBLEM TO BE SOLVED: To provide the slurry of calcium hydroxide ultrafine particles being stable in long term dispersion. SOLUTION: The calcium hydroxide ultrafine particles in the slurry have a median diameter (d50) in a passing portion cumulative distribution of 0.5μm or less and d90-d10 in the passing portion cumulative distribution of 0.5μm or less. It is favorable that the slurry involves calcium hydroxide of 5-60 pts.wt., a dispersing agent of 0.01-30 pts.wt. and water of 10-94.99 pts.wt. COPYRIGHT: (C)2007,JPO&INPIT
