<p>PROBLEM TO BE SOLVED: To secure a good grinding property by suppressing the solidification of a grinding obtained by dispersing a grinding material in an aqueous in an aqueous solution, cased by coagulation and gelation with time, for improving its handling property. SOLUTION: In this grinding liquid 16 consisting of a grinding material and an aqueous solution, and used for grinding a material to be ground 5, a water to be used has <=0.500μS/cm (at 25 deg.C) electric conductivity and the content of polyvalent ions is reduced, etc. to suppress coagulation.</p> |
