Washington Mills: DURALUM AB- Tiny Bubbles Can Save You Big Energy

Washington Mills manufactures hollow insulating spheres, otherwise known as alumina bubbles, made from high-purity alumina. Alumina bubbles act as a versatile and lightweight refractory mineral. Alumina bubble’s unique structure makes it an excellent insulating material that has low thermal conductivity and can withstand exceptionally high temperatures. Bubble alumina’s superior insulating properties will keep an outer shell cooler or help a kiln maintain a steady temperature. The alumina bubbles do an excellent job of insulating and keeping the heat inside of the furnace. The better your refractory is insulated, the more energy you will save, and the more money you will save.
