Definitions

  • the method of the CVI is also limited to compounds that can be separated from carrier gases by reaction of the components, which also limits the substances available for the thermal insulation materials.
  • the volume ratio of ceramic particles to organic short fibers according to the invention is 0.5 to 4 parts by volume ceramic particles to 1 part by volume short fibers, preferably 0.8 to 2.5 parts by volume ceramic particles to 1 part by volume short fibers.
  • the sintered plate has a density of 0.3 g / cm 3 and consists microscopically of polycrystalline Ca-Al-silicate ceramic threads which are connected to one another at the contact points.
  • the threads have a diameter between 10 and 20 ⁇ m and are on average 1 mm long.
  • the material has a flexural strength of 5 MPa and a thermal conductivity of 0.07 W / mK at 80 ° C.

Abstract

L'invention est relative au domaine des matériaux calorifuges céramiques et concerne un matériau isolant pouvant être utilisé dans la construction de fours et de foyers, dans des chambres de réaction chimique ou en aérospatial. L'objectif de cette invention est de produire un matériau calorifuge à propriétés calorifuges comparables ou supérieures à celles de matières isolantes fibreuses. A cet effet, ce matériau est produit selon un procédé dans lequel des fibres courtes organiques sont dispersées dans un liquide, lequel liquide est une suspension contenant des particules céramiques et au moins des agents de liaison. Ensuite, ces particules céramiques et ces agents de liaison sont déposés par coagulation sur les fibres courtes organiques, ces fibres sont séparées puis les particules céramiques sont frittées.
