Fused Silica
Silice Electrofondue
/ Quarzgut
elektrogeschmolzen
A high quality Fused
Silica with extensive
use in the production of
refractories, crucibles,
foundry cores and mild
abrasives.
Produced from
electrofusion of
selected quartz sand.
Properties are:
- Excellent thermal
shock resistance
- Extremely low
thermal expansion
- Zero glass content
- Controlled surface
properties
- Totally amorphous
crystal structure (XRay
Diffraction)
Cermatco is able to give
complete specifications
for an iron-free material
down to ppm levels.
