Metal and ceramic sintered bodies and coatings are produced using a combination of:

Method for producing metal and ceramic sintered bodies and coatings

The present invention relates to a process for the preparation of finely divided metal and/or ceramic powders by reacting appropriate metal compounds and appropriate reagents in the gas phase (CVR) chemical vapor reaction, wherein the metal compound(s) and the further reagents are brought to reaction in the gaseous state in a reactor and are subsequently homogeneously condensed directly out of the gas phase, with exclusion of any wall reaction, and are subsequently separated from the reaction medium.

Process for the preparation of finely divided metal and ceramic powders

This invention relates to fine-particle powders of the metals B, Al, Si, Ti, Zr, Hf, V, Nb, Ta and/or Cr which have a defined particle size of 1.0 nm to less than 3 .mu.m. Less than 1% of the individual particles of the powder deviate by more than 40% from the average particle size, and no individual particle of the powder deviates by more than 60% from the average particle size.

Fine-particle metal powders

This invention relates to fine-particle powders of the metals Fe, Co, Ni, W and/or Mo which have a defined particle size of 1.0 nm to less than 1 00 nm. Less than 1% of the individual particles of the powder deviate by more than 40% from the average particle size, and no individual particle of the powder deviates by more than 60% from the average particle size.

The invention relates to fine non-oxide ceramic powders MeX, wherein

Fine non-oxide ceramic powders

The invention relates to fine-particle oxide ceramic powders of the metal oxides MeO, where

Fine-particle oxide ceramic powders

The invention relates to a gas phase reactor for producing finely divided metal and/or ceramic powder and comprising a gas preheater, a gas-introducing part, a flow-shaping part, a reaction tube and a product discharge device.
