Scope Notes

Glossary: ceramics inorganic, non-metallic products obtained by a process involving a shaping step and a sintering or comparable heat treatment step, with the exclusion of cements, cermets and glasses, glazes, vitreous enamels and devitrified glass ceramics fine ceramics ceramics having a polycrystalline fine-grained microstructure, e.g. of dimensions below 100 micrometer refractories ceramics or mortars withstanding high temperatures of at least about 1500 degrees C. For classification and search in this subclass, no substantial distinction is made between the terms "refractories" and "ceramics" carbon-carbon composites products consisting of carbon fibres in a carbon matrix are usually referred to as "carbon-carbon composites" porous materials materials which are deliberately made porous, e.g. by adding gas-forming, foaming, burnable or lightweight additives to the composition they are made of | Limiting references: Mechanical features relating to the working of ceramics, e.g. mixing or shaping ceramic compositions Devitrified glass ceramics Clay-wares Compositions containing free metal bonded to carbides, diamond, oxides, borides, nitrides, silicides, e.g. cermets, or other metal compounds, such as oxynitrides or sulfides, other than as macroscopic reinforcing agents Manufacture of ceramic fibres Furnaces, kilns, ovens, or retorts Casings, linings, walls, roofs of furnaces, kilns, ovens, or retorts | Application references: Dental prostheses, e.g. porcelain or ceramic teeth Materials for prostheses or for coating prostheses Materials for catheters or for coating catheters Materials for other surgical articles Luminescent materials Fireproofing materials Materials for coating by flame or plasma spraying Materials for coating by sputtering, e.g. ceramic targets Materials for parts of bearings, e.g. sliding-contact bearings Materials for friction linings Materials for pistons, trunk pistons, plungers Materials for piston-rings or seats therefor Materials for rigid pipes Materials for protection of pipes or pipe fittings against corrosion or incrustation Luminescent materials for light screens Materials for conductors or conductive bodies Materials for insulators or insulating or dielectric bodies Superconductive or hyperconductive conductors, cables, or transmission lines Materials for varistor cores Materials for magnets or magnetic bodies Superconducting magnets or coils Materials for fixed capacitors, e.g. ceramic dielectrics Materials for superconductive or hyperconductive devices Materials for piezo-electric or electrostrictive elements Materials for inert electrodes with catalytic activity for electrochemical generators, e.g. for fuel cells Materials for solid electrolytes of fuel cells Dielectric resonators of the waveguide type Details of semiconductor or other solid-state devices characterised by the material, e.g. ceramic substrates
