YUFENGREC® Refractory Sagger Kiln Furniture are made of top quality tabular alumina , fused corundum,mullite , applied with advanced ultrafine powder adding technology. by mixing, drying and forming, and fired in a high-temperature shuttle kiln.
The sagger has the characteristics of compact structure, high compressive strength, good thermal shock resistance, acid and alkali corrosion resistance, anti-flaking, anti-powdering and long service life. The products are widely used in the melting of rare earth magnetic materials, alloy materials and the sintering of ceramic powders.
Special shapes can be customized as per the requirements of customers.
