1. Details
Cordierite ceramics are well known for their low thermal expansion
and refractory character. Although cordierite is available as a
powder, when we use the term we are generally talking about ceramic
that went into the kiln as ordinary composite of ceramic powders
but emerges as a cordierite crystalline matrix (grown by the firing
process tuned to its needs).
2. Features
A. Weight reduction of approximately 35% - 50%, whilst increasing
the load capacity of the batt. For example, a 38mm-thick extruded
batt has the same weight as a 23mm-thick pressed batt of the same
size, but can bear 5 times the load.
B. Energy Savings. Tests have shown that using extruded batts in a
shuttle kiln firing glass panels, fuel consumption can be reduced
by between 30% and 70%.
C. Reduced bend at high temperatures. 1200mm long extruded batts
supported by silicon carbide beams have shown virtually no bend
during use. This is extremely useful where flatness is critical,
such as in the firing of glass panels.
D.Their ability to disperse heat is twice that of a solid batt of
similar size, allowing them to bear extremes of hot and cold much
better, thereby increasing their service life. This makes extruded
batts especially suitable for faster firings.
