摘要:Heating an aqueous mixture of a fluoroacid such as H.sub.2 TiF. sub.6 and anoxide, hydroxide, and/or carbonate such as silica produces a clear mixture with long termstability against settling of any solid phase, even when the oxide, hydroxide, or carbonatephase before heating was a dispersed solid with sufficiently large particles to scatterlight and make the mixture before heating cloudy. The clear mixture produced by heatingcan either be mixed e with water soluble and/or water dispersible polymers that arepolyhydroxyalkylamino- substituted polymers and/or copolymers of p-vinyl phenol, orwith soluble hexavalent and/or trivalent chromium, to produce a composition thatimproves the corrosion resistance of metals treated with the composition, especiallyafter subsequent painting.
