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 Youngâs
modulus values. |
