Abstract
Compositions of nickel, iron and phosphorus, are prepared by fusing nickel and ferrophosphorus in an inert atmosphere, with the nickel preferably comprising from about 5% to about 70% by weight of the composition. The fused composition is ground or atomized to form a conductive, corrosion resistant pigment, preferably having a particle size of from about 0.1 to about 15 microns. This pigment can then be incorporated into a suitable resin binder, optionally with one or more other suitable metals such as zinc or nickel, to prepare corrosion resistant coatings, weldable coatings, EMI shielding coatings, electrostatic dissipation coatings, or electrically conductive coatings.
Claims18
A method of making a fused composition of nickel, iron, and phosphorus comprising
- (1) fusing at a temperature of at least about 1455.degree. C. a mixture of
- (a) about 5 to about 70% by weight nickel;
- and
- (b) about 30 to about 95% by weight ferrophosphorus, where said ferrophosphorus contains about 20 to about 28% by weight phosphorus;
- (2) allowing the fused mixture to cool to form a solid mass;
- and
- (3) comminuting said solid mass to form particles.
A coating composition having a non-volatile content comprising about 5 to about 50 percent by weight of a binder and from about 50 to about 95 percent by weight of a
A coating comprising
- (1) about 5 to about 50% by weight resinous binder;
- and
- (2) about 50 to about 95% by weight pigment particles which comprise a fused composition of
- (a) about 5 to about 70% by weight nickel;
- and
- (b) about 30 to about 95% by weight ferrophosphorus, where said ferrophosphorus contains about 20 to about 28% by weight phosphorus.
