	Fused alumina for refractory products has a high melting point and is widely used for shaped and unshaped refractory products due to its high refractoriness under load. Hollow Sphere Fused Alumina BL is high-purity alumina with low SiO2/low Na2O with fewer broken spheres, and its heat isolating property is excellent.

Applications

Heat insulating brick

Lightweight refractory products

Special grinding wheels
