Abstract
Bake out is accelerated and made possible at a lower temperature when at least one metal organic compound defined by the general formula M R.sub.n in which M=V.sup.III, Mn.sup.II, Mn.sup.III, IN.sup.III, Ca, Co.sup.III, Ni.sup.II (VO).sup.II or (VO).sup.III n=2 or 3 R=an organic residue of the compound classes of polyunsaturated compounds, aminoalcohols, aminoacids, carboxylic acids, hydroxycarboxylic acids, mercaptocarboxylic acids, enolisable ketones, ketoximes, aldoximes, amines, and phosphines which is capable of changing into an oxide of M when heated to 150.degree. to 420.degree. C. is dissolved in the starting mixture or added to the starting mixture in the form of a solution.
Claims8
In the method of forming a molding or a layer of an inorganic material by forming a mixture of said inorganic material and a polymeric organic material, molding said mixture into a desired configuration or depositing a layer of said mixture on a substrate and then removing said polymeric organic compound from the resultant molding or layer by subjecting said layer or molding to baking at a temperature of from 150.degree. C.-420.degree. C. for a time sufficient to cause said polymeric organic compound to be volatilized and removed, the improvement wherein prior to the baking there is added to said mixture a metallic organic compound of the general formula M Rn wherein
- M=V.sup.III, Mn.sup.II, Mn.sup.III, In.sup.III, Ca.sup.II, Co.sup.III, Ni.sup.II, VO.sup.II or VO.sup.III
- N=2 or 3 and
- R=an organic residue of polyunsaturated compounds, carboxylic acids, enolisable ketones, ketoximes, aldoximes, amines or phosphines,
- and capable of being converted to an oxide of M when heated to 150.degree. C.-420.degree. C.
