Anisotropic zinc phosphate particles and zinc metal mixed phosphate particles having an orthorhombic crystal structure and a platelet-shaped particle morphology are obtained from a composition comprising at least one phosphate compound; at least one zinc compound and at least one chelate complexing agent having at least two oxygen-containing groups and at least one solvent.

Method for producing anisotropic zinc phosphate particles

The aim of the invention is to create a composition for coating electric conductors which is significantly more resistant to partial discharges than prior art compositions while the produced insulating layer is highly extensible. Said aim is achieved by a composition comprising 1 to 50 percent by weight of microparticles that have a specifically adjusted electronic defect structure in the crystal lattice, resulting in greater polarizability of the valence electrons, and an organic and/or organic-inorganic matrix. The microparticles that have a specifically adjusted electronic defect structure are composed of oxides, sulfides, selenides, tellurides of the elements which are part of the series encompassing silicon, zinc, aluminum, tin, boron, germanium, gallium, lead, the transition metals, lanthanides, and actinides, particularly from the series encompassing silicon, titanium, zinc, yttrium, cerium, vanadium, hafnium, zirconium, nickel, and/or tantalum, in such a way that the basic lattice is provided with vacant lattice positions by doping 4 the basic lattice with adequate low-valent or higher-valent elements, said vacant lattice positions increasing the electronic polarizability of the microparticles by means of defect chemistry (the defect structure).

Coating composition for electrical conductors and method of producing such a composition

The invention relates to a coating composition consisting of an oxide compound. The invention also relates to a method for producing a coating composition consisting of an oxide compound and to a method for coating substrates composed of metal, semiconductor, alloy, ceramic, quartz, glass or glass-type materials with coating compositions of this type. The invention further relates to the use of a coating composition according to the invention for coating metal, semiconductor, alloy, ceramic, quartz, glass and/or glass-type substrates.
