Ceramic Methods

The most common method of preparing metal oxides and other solid materials is by the ceramic method, which involves grinding powders of oxides, carbonates, oxalates or other compounds containing the relevant metals and heating the mixture at a desired temperature, after pelletizing the material

  • The most common method of preparing metal oxides and other solid materials is by the ceramic method, which involves grinding powders of oxides, carbonates, oxalates or other compounds containing the relevant metals and heating the mixture at a desired temperature, after pelletizing the material
  • It is sometimes difficult to obtain compositionally homogeneous products by the ceramic technique even when the reaction proceeds almost to completion. In spite of such limitations, ceramic techniques have been successfully used for the synthesis of a variety of solid materials
  • Bulk as well as nanocrystalline phases of metal oxides, nitrides and carbides are often synthesized by employing carbothermal reactions
  • Iron particles are likely to facilitate the removal of oxygen from the silica
  • The iron oxide formed in such a reaction would readily get reduced back to metal particles in the reducing atmosphere
