Product Description

Product Description

 

1.Cordierite-Mullite kiln furniture is composed of cordierite, mullite and glass phase.

2.Due to the high temperature resistance of mullite and the low expansion of cordierite, Cordierite-Mullite kiln furniture has excellent thermal shock resistance,long service time,can be safety used at temperature below 1350.

3.Extruded batts are the most common type of primary kiln furniture, usually produced by semi-dry pressing, but can also be made by pressure-casting. Extruded batts can be split into ten sub-categories as follows: Extra Large Batt, Extra Thin Batt, Plain Batt, Perforated Batt, Grooved Batt,Trapezoid Batt, Recessed Batt, Full Disc, Half Disc and Special Batt.
