Cordierite Mullite Extruded Batts

Introduction:
Cordierite-Mullite  is a combination of Cordierite Phase ,Mullite Phase and Glass Phase , feature with excellent thermal shock  resistance ,high temperature resistance ,which is the most suitable  material making  kiln furniture especially service  under 1300 Deg C.
Extruded batts can be split into : Extra Large Batt, Extra thin Batt, Plain Batt, Perforated Batt, Grooved Batt, Trapezoid Batt, Recessed Batt, half Disc and Special Batt.

Features:
1.Extremely  Thermal Shock Resistant.
2.Stable under high temperature.
3.Low density.
4.Excellent dimensional accuracy control.

Application:
Cordierite-Mullite Kiln Furniture  are  widely used in the Table Ware , Sanitary ware , Electrical Porcelain Insulator , Powder Calcination , Technical Ceramic industry.
