• material
  • The plant, south of the Aluminium Bahrain (Alba) complex, will primarily produce fertiliser while prospects exist for using the aluminium oxide for making ceramics and material such as cool decks for which Taha has devised a way that allows less than 50 per cent of the sun's heat to be absorbed.

  • Cellular ceramic articles are produced in accordance with the present invention by immersing an open-celled porous element of pliable synthetic or natural organic material in a slurry of finely-divided ceramic powder plus ceramic binder so as to uniformly coat the inner celldening walls of the element with a thin layer of the slurry. (google.com)
  • After the excess slurry is removed from the ceramic-coated porous element, the latter is fired to completely vaporize and burn out the organic material and, if desired, to vitrify the ceramic. (google.com)
  • The binder in the slurry is important to eliminate the danger of the ceramic articlcs collapsing during or after removal of the organic material and before the ceramic has vitried. (google.com)
  • This latter material is available commercially in a large variety of open cell sizes ranging from a struc- Patented May 21, 1963 ture having extremey small cells, which is desirable for the manufacture of ceramic filters, to a large cell structure, which appears preferable where the ceramic article is to be used as a catalyst carrier.

  • structure
  • The invention has as its principal object the provision of a Simple, inexpensive method for manufacturing opencelled, porous ceramic articles affording excellent control over the precise cellular structure and external shape of the finished articles. (google.com)
  • include
  • If the porous ceramic article being manufactured is intended as a catalyst support, the ceramic may include any of the well-known catalytic oxides, such as chromium oxide, nickel oxide, copper oxide or vanadium pentoxide, which are useful as hydrocarbon oxidation catalysts for engine exhaust gas catalytic afterburners and the like.
