A METHOD FOR SIDPERSING SODIUM NITRITE IN A LUBRICATING COMPOSITION WHICH COMPRISES: (A) DRY GRINDING SODIUM NITRITE TO FORM A MICRONIZED SODIUM NITRITE HAVING AN AVERAGE PARTICLE SIZE WITHIN THE RANGE OF 5 TO 40 MICRONS AND A WATER CONTENT OF LESS THAN 0.1 WT. PERCENT, (B) DISPERSING THE MICRONIZED SODIUM NITROTE IN OIL TO FORM AN OIL DISPERSION WHEREIN THE WEIGHT RATIO OF SAID MICRONIZED SODIUM NITRITE TO SAID OIL IN SAID OIL DISPERSION IS FROM 0.5:1 TO 1.5:1, AND (C) MIXING SAID OIL DISPERSION INTO SAID GREASE COMPOSITION AR A TEMPERATURE OF LESS THAN 150*F.
