A method is described to produce magnesium fluoride sols in an alcohol, especially in ethanol, with improved properties by the reaction of magnesium acetate or magnesium alcoholate with HF in C1 to C3 aliphatic alcohol or C2 or C3 aliphatic diol, preferably ethanol, in the presence of a specific amount of water. n Improved magnesium fluoride sols are also described. The sols are useful to provide coatings of MgF 2 on solar cells. n The invention also provides solutions containing magnesium acetate, specific organic solvents, carbon dioxide and optionally water. |
