Nickel Slag Air-cooled nickel slag is brownish-black in color. It crushes to angular particles but has a smooth, glassy texture. The specific gravity of air-cooled nickel slag may be as high as 3.5 (15), while the absorption is quite low (0.37 percent). (3) The unit weight of nickel slag is somewhat higher than that of conventional aggregate. ...
