kiln furniture

Detailed Product Description

The picture showing above is sagger, a kind of kiln furniture. This is the T-130 type, with Al2O3 50%, and the max work temp is 1300deg.

DOUBLE EGRET specializes in refractory and insulation material in north of China, productions covering dordierite-mullite products, refractory bricks, ceramic fiber products etc.

Kiln furnitures for kilns are high-grade,selected mullite and cordierite as raw materials,
adopted advanced technology, including slab, sagger, muffle plate, rack, base plate, strut.
The refractoriness of the kiln furniture (combined mullite with cordierite) is better than
cordierite, the thermal stability is superior
compared with mullite corundum material.
Characteristics:
Low thermal expansivity
Resistance to thermal shocks
No abrupt failure
Nonoxidizable
Antifouling
