White Fused Alumina
Edelkorund /
Corundum
A high quality
electrofused
corundum. Processed
in the UK to ensure
total logistical and
quality control. Good
quality blocky grains
developed iron-free .
Produced from high
temperature sintering
of Bayer process low
soda content calcined
alumina.
Major phase identified
by X-Ray Diffraction as
massive corundum. No
other discrete phases
identified. WFA
enables complete
control of the
chemistry and physical
properties promoting
complete control of the
final ceramic or
refractory system.
Produced in normal
FEPA Macro grit sizes
with other particle size
distributions available
on request including micronised varieties.
