PRODUCTION OF LEAD TITANATE

摘要

PURPOSE:To eliminate the need for such constraint in a conventional method that a nitric acidic titanium oxide aq. soln. is stored by refrigeration and tightly stoppered by adding oxalic acid of the specified amount to the nitric acidic titanium oxide aq. soln. and converting it into oxalate compd. stable for a long period and soluble in water. CONSTITUTION:About 1.5mol oxalic acid per 1mol nitric acidic titanium oxide is added to a nitric acidic titanium oxide aq. soln. and it is converted into oxalate compd. stable for a long period and soluble in water. This soln. is brought into contact with an aq. soln. contg. lead compd. equivalent to nitric acidic titanium oxide to produce precursor precipitate of lead titanate. Lead titanate is produced by subjecting the precursor precipitate to pyrolysis in an oxygen atmosphere.
