White Fused Mullite
Schmelzmullit / Mullite Electrofondue
A high quality White
Fused Mullite with
extensive use in the
production of steel,
glass and ceramic
refractories.
Produced from
electrofusion of Bayer
process calcined
alumina with selected
low iron silica.
Major phases identified
by X-Ray Diffraction as
mullite with traces of
glass and corundum.
Mullite - the most
stable phase of the
alumino-silicate
system, is found rarely
in nature and is
inevitably subject to
contamination from
other rock formations
and contaminants.
Synthetic mullite
enables complete
control of the
chemistry and physical
properties promoting
complete control of the
final ceramic system.
Individual crystallites
are in the order of 50
mm in length and are
formed, on cooling
from the melt to provide discrete crystals of mullite exhibiting:
- high thermal shock resistance
- low thermal expansion
- low glass content
- controlled surface properties
- excellent creep resistance
Cermatco is able to give complete specifications for an
iron-free material down to ppm levels.
