<p>Crystalline aluminates of the formula: I. Li(R)??2Al(OH)3?nH2O, or II. Mm(R)?(A)??2Al(OH)3?nH2O where nH2O is zero or any required waters of hydration; R is a monocarboxylic acid or dicarboxylic acid of C6-C22, including those which are OH- substituted; r is greater than zero and represents the number of R ions in the molecule; v is the valence of R, being monovalent or divalent; M is divalent Zn or Ca cations; A represents inorganic anions of valence 1-3, represented by w; y is equal to or greater than zero and represents the number of A anions; wherein, in formula I, vr represents an amount of R anions to substantially satisfy the valence requirements of Li; 32,399A-F wherein, in formula II, r>y and (vr + wy) represents an amount of combined anions, R and A, to substantially satisfy the valence requirements of M; with m representing the number of divalent M cations and having a numerical value in the range of about 1 to about 4, are found to improve the coefficient of friction and antiwear properties of lubication fluids subjected to shearing, rubbing, or grinding forces at elevated pressure. 32,399A-F</p> |
