Refractory triangle Cordierite kiln shelf and kiln furniture for ceramic bowl
1. Introduction
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
Excellent energy savings
Lighter weight and higher load capacity
Excellent distortion resistance at high temperature
Suitable for faster firings with better bearing capacity for hot
and cold extremes
As noted, a continuous crystal matrix is the object of cordierite
creation (not just the presence of the crystals in an otherwise
typical ceramic). Notwithstanding this, cordierite powder is
available, it is prefired and finely ground. It can be plasticized
for forming and bonded during firing (at much lower than normal
cordierite creation temperatures) to produce a ceramic that
certainly has lower expansion.
