Tunnel Kiln Cordierite Kiln Shelves Slabs Energy Saving For Ceramic Insulator

Kam Tai refractory Cordierite slab 360*310*20mm for tunnel kiln

1. Introduction 

Cordierite has excellent thermal shock resistance, good strength and can be formed by pressing, extruding, casting and vibrating into complex shapes. Cordierite mullite kiln furniture is widely used in porcelain, heavy clay, glass panel, powder metallurgy, magnetic materials, green energy, food, glass, abrasives, iron and steel, mining and aerospace engineering.
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.
The practicality of cordierite, as a refractory, can be better appreciated when comparing it to alumina. Although alumina by itself, is more refractory than cordierite, it is also much more prone to cracking when subjected to thermal shock. By comparison, cordierite has low expansion and much less expensive. No wonder that cordierite kiln shelves are common.
While cordierite ceramic vessels could be made (e.g. ovenware), the material has such a low thermal expansion it is very difficult (or impossible) to match a glaze (without crazing). Notwithstanding this, many recipes can be found for cordierite ovenware or flameware. However these are seldom fired above cone 10 so any thermal shock resisting behavior they have is attributable to grog content or open fired matrix rather than to any cordierite development (which is of course not happening).
