Abstract:

Layered alumino-silicate composites, used as refractories, are studied to

determine their thermomechanical behavior through a thermal treatment up to 1550°C.

Reactions in the matrix and matrix-particle interactions create a secondary mullitization

(~24 wt.% increase of mullite amount) in the structure that consequently strengthens the

material. Samples with higher pore volume fractions exhibit lower overall Young’s

modulus values.

Keywords:

Refractory, Mullite, Thermomechanical Properties.
