Abstract:
1. A compound of the formula: A x B y Cit 2 F z , wherein: A is a cation selected from the group consisting of the Periodic Table IA metal ions lithium (Li), sodium (Na), and potassium (K) and the Periodic Table IIA metal ions Magnesium (Mg) and Calcium (Ca); B is a cation selected from the Periodic Table IIA metal ions Magnesium (Mg) and Calcium (Ca), and the Periodic Table divalent d-block transition metal ions Copper (Cu) and Zinc (Zn); A and B are different; “Cit” is tribasic citric acid anion; the ratio of x to y is equal or higher than 1.0 but lower than 8.0; z is selected such that electroneutrality is preserved; and wherein z is adjusted so that when A and B are both selected from ions having a valence of plus 2, 2x+2y is equal to z+6; or wherein z is adjusted so that when A is selected from ions having a valence of plus 1 and B is selected from ions having a valence of plus 2, x+2y is equal to z+6; and wherein said compound comprises fluoride.
