Process for producing weakly agglomerated nanoscalar particles

The invention is directed to a method for producing low sintering fine-particle multicomponent glass powder having a particle size of the primary particle in the nanometer range. The method utilizes microemulsion techniques with subsequent separation of the particles out of the emulsion and calcination for utilization as glass flow having a sintering temperature &lt;900.degree. C. or in a glass flow, for generating thin transparent layers or for generating color decorations on glass, glass ceramic or ceramic substrates after adding a coloring pigment to the glass flow. The microemulsion for producing the nanoscale glass powder particles is generated from a nonionic ambiphilic emulsifier with a component of 10 to 15 percent by weight on the emulsion, from an oil phase having a portion of 50 to 70 percent by weight and a glass precursor-containing aqueous salt solution having a portion of up to 31.3 percent by weight with salt contents of up to 45 percent by weight.

Method for producing metal and ceramic sintered bodies and coatings

A process is described for fixing an inorganic species in an organic matr which comprises bringing a compound of the formula MR.sub.n in which M is selected from sub-group metals, lanthanides, actinides, Al, Sn, B and Si, and the radicals R can be replaced by a complexing agent, into contact with a complexing agent, the complexing agent containing a functional group which is capable of participating in a polymerization or polycondensation reaction. After complexing, hydrolysis and condensation are preferably first carried out, followed by polymerization or polycondensation.

Process for fixing inorganic species in an organic matrix

A novel process is described for the preparation of monodisperse ceramic ders wherein particulate oxides or hydroxides are obtained by reaction of hydrolysable compounds with water. The reaction is carried out in the presence of a complexing agent and, optionally, a stabilizer.
