Applications of Corundum Mullite Bricks
Corundum mullite bricks are exceptional refractory materials known
for their heat resistance. They're widely used in industries like
steel, ceramics, and glass for lining furnaces, kilns, and
high-temperature equipment. These bricks withstand extreme heat,
making them ideal for steelmaking, petrochemicals, cement, glass
manufacturing, and waste treatment plants. Their resilience against
high temperatures and corrosive environments makes them
indispensable in numerous industrial applications.
