    Abstract: A process for the production of an aqueous lubricant composition free of oil including water and at least one metallic carboxylate, wherein the anionic is at least one saturated linear organic radical containing at least 12 carbon atoms and the cationic is at least one bivalent or trivalent metal having an electro-chemical oxidation-reduction potential greater than -0.7 volts. The process includes mixing of two mother solutions. The first mother solution is an aqueous solution of at least one alkali metal carboxylate soluble in water wherein the anionic is at least one saturated linear organic radical with at least 12 carbon atoms. The second mother solution is an aqueous solution of at least one metallic salt whereof the anionic is selected from the group consisting of hydroxide, chloride, sulphate, nitrate or phosphate ions and whereof the cationic is at least one bivalent or trivalent metal having an electro-chemical oxidation reduction potential greater than -0.70 volts.

    Abstract: A novel lubricant composition is disclosed, which contains not less than 0.1% by weight of at least one calcium ferrite having the following general formula:Ca.sub.x Fe.sub.y O.sub.x+(3/2)ywherein x is 1 or 2 and y is 2 or 4, provided that y is 2 or 4 when x is 1, and y is 2 when x is 2. The calcium ferrites may be monocalcium ferrite, dicalcium ferrite or hemicalcium ferrite, produced by mixing iron oxide and a calcium compound in a molar ratio of 1:0.5 to 1:2 and fusing them by heating at a temperature of 1200.degree.-1400.degree. C. The resultant material contains not more than 5% by weight of the whole, of ferric oxide, silica and alumina as impurities. The calcium ferrites have a maximum particle size of 100.mu., preferably 0.15.mu.. They can be used as such for lubricant purposes, or can be incorporated in a lubricating oil or grease, such as a mineral oil, in an amount more than 0.1% by weight and preferably more than 1% by weight.
