Patent ID: 8591611

Claim:
An aqueous slicing slurry comprising 100 parts by weight of an aqueous slicing fluid and 50 to 200 parts by weight of silicon carbide, wherein the aqueous slicing fluid comprising (A) 0.01 to 20% by weight of a modified silicone selected from the group consisting of polyether-modified silicones, amino-modified silicones, carboxyl-modified silicones, and epoxy-modified silicones, (B) 1 to 20% by weight of water, and (C) 60 to 98.99% by weight of diethylene glycol and polyethylene glycol wherein the modified silicone is one represented by the following average compositional formula (1): R 1 p R 2 q R 3 r SiO (4-p-q-r)/2 (1) wherein R 1 is —(CR 4 2 ) n X, R 4 is hydrogen atom, a substituted or unsubstituted monovalent hydrocarbon group having 1 to 20 carbon atoms and having no aliphatic unsaturated bond, or hydroxyl group, n is an integer of 1 to 20, X is a functional group selected from the group consisting of an amino group, carboxyl group and epoxy group, R 2 is a substituted or unsubstituted monovalent hydrocarbon group having 1 to 20 carbon atoms and having no aliphatic unsaturated bond, R 3 is an organic group having the general formula: —C f H 2f O(C g H 2g O) h R 5 , R 5 is hydrogen atom, a substituted or unsubstituted monovalent hydrocarbon group having no aliphatic unsaturated bond, or acetyl group, f is a positive number of 2 to 12, g is a positive number of 2 to 4, h is a positive number of 1 to 200, and p, q and r are numbers satisfying 0≦p<2.5, 0.01≦q<2.5, 0≦r<2.5 and 0.05<p+q+r≦3.0.
