Low Expansion Rate Refractory Cordierite Grooved Batts 400*350*15mm
1. Introduction
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).
Cordierite makes the ceramic manufacture of products like catalytic
converters possible. They constantly heat up and cool down quickly
and must not crack because of the shock. These converters get their
thermal shock resistance properties from a bonded matrix of
low-expansion cordierite crystals. These crystals form during
firing between 1300 to 1400C (interestingly, cordierite crystals
have a lesser thermal expansion along one axis than another). Thus,
the better the density of the precursor mix and controlled the
firing the better the properties of the cordierite material are.
2. Details
Increased load capacity
• Easier lifting in and out of kilns due to lighter weight
• Easier on operators’ hands since all edges and corners are smooth
and rounded
• Less need for full shelves since half shelves remain flat
indefinitely
• Significantly less (if any) scraping, grinding and other
time-consuming messy or dusty prep work between firings
• Reduced firing costs over time
• Faster firing cycles, if desired
