Uses For Aluminium Hydroxide

  • For the manufacture of aluminium and aluminium compounds
  • As a fire retardant
  • Ceramics and pottery


In ceramics it is used primarily to promote 'stiffness' of glazes (6-10% of silica content). Increasing firing temperature and resistance to chemical attack. In larger quantities (15% of glaze) however, produces opaque and matt effects. Also used on kiln shelves as protection against glaze sticking.
