PRODUCT DESCRIPTION：YONAI Fused Mullite YFM
YONAI Fused Mullite is produced by the electric furnace fusion of alumina and high purity silica.
YONAI Fused Mullite (YFM) is a mineral of needle like alumina silica grain that has low conductivity, excellent thermal shock resistance, and excellent resistance to deformation under load. YFM is used in application such as refractories for glass and steel industries as kiln furniture, in investment casting as shell building materials, in spark plug bodies, and many other applications.
