Sintered mullite

Sintered mullite

  Sinocean sintered Mullite is made of natural high-quality bauxite, through multi-level homogenization, calcined at over 1750℃.  As it is sintered under controlled conditions ,Sintered Mullite consists of well grown crystals of Mullite in a very large quantity,.which makes it has a high melting point, excellent resistance to thermal shock, excellent stability under load and good resistance to slag and metal corrosion.

 

Application

  • Mullite firebrick
  • Refractory motar
  • Refractory castable
  • Insulating firebrick
  • Ramming mix
