Subtitle

Sintered mullite 75% alumina

Description

Good corrosion resistance to alkali vapours. Available in standard brick format.

Typical application

MS 75 is used in:

  • regenerator chamber target walls and crowns,
  • superstructures breastwalls for reinforcement and textile fiber glass furnaces as well as sodium silicate furnaces.

Intermediate creep resistance between MS 6 and BP MULLITE.

If mortar is required, use MULLITE MORTAR or BP MULLITE MORTAR.
