摘要
The mixt. contains an abrasive, a metal powder and 1-14.5 wt.% of at least two salts contg. Cl, F and/or B, with different m.pts. The pref. salts include B2O3, H3BO3, borofluorides, double salts, and/or a eutectic mixt. of usch salts, e.g. chlorides. The mixt. is compaced and sintered to make tools for grinding hard alloys and brittle non-metallic materials. The salts acts as fluxes removing oxide films from the metal powder and lowering the sintering temp.
