Mullite (3Al2O32SiO2) is a refractory oxide material combining low thermal expansion, good mechanical strength, and resilience at elevated temperatures. McDanel Mullite is formulated to produce dense, impervious shapes, with optimized thermal shock resistance and strength.
MV20 and MV-HR1 are dense mullites formulated to offer high quality economical options for moderately high temperature applications.
MV30 is an extremely versatile and economical material. Its workability allows an extensive range and flexibility in fabrication. It is well suited for the casting of special shapes and larger tubes.
