Alumina Brick Applications
Alumina or high alumina bricks are bricks that are supposed to provide protection against high heat. These bricks are utilized in a variety of applications. The most prevalent for these bricks is within glass melting tanks. They may be sometimes called fire bricks.
Alumina bricks can also be utilized to line fireplaces, furnaces, and kilns. Besides being proof against high heat temperatures they can also hold onto their heat for prolonged periods. This allows them to provide greater efficiency for things like furnaces or fireplaces.
These bricks comprise about fifty percent alumina. This makes them similar in makeup to fireclay bricks. Fireclay bricks have only about forty percent alumina. The exact content from the alumina has much concerning the standard of the brick. Alumina bricks do not have porous surfaces hence they also expand if they are in contact with high heat temperatures. They could withstand temperatures in excess of 2900 degrees F.
While they can expand they are not the very first selection for high-temperature primary bricks. They can be, however, much better suited to backup bricks. The better the content of your alumina the better off of the bricks are for industrial uses. Also, they are sometimes created from alumina and chrome making them excellent for industrial uses that will expose the bricks to both cold and hot temperatures. They can be resistant against acidic slags.
The alumina within the bricks enables them to have good load bearing capabilities. Again, this is exactly what makes them endure in even the toughest conditions in industrial uses. To enable them to be regarded as high alumina they should be produced mostly of lower alumina silicates or clay.
These bricks have excellent load resistance in industrial uses after they contain some mullite crystals. They may be purchased online from quality manufacturers.
