Alumina Brick Applications

Alumina or high alumina bricks are bricks that are made to provide protection against high heat. These bricks are used in a variety of applications. The most common for these bricks is in glass melting tanks. They are sometimes called fire bricks.

Alumina bricks are also used to line fireplaces, furnaces, and kilns. Besides being resistant to high heat temperatures they can also hold onto their heat for extended periods. This allows them to provide greater efficiency for things like furnaces or fireplaces.

These bricks are made up of about 50 percent alumina. This makes them similar in makeup to fireclay bricks. Fireclay bricks only have about 40 percent alumina. The actual content of the alumina has much to do with the quality of the brick. Alumina bricks do not have porous surfaces so they also expand when they are exposed to high heat temperatures. They can withstand temperatures of over 2900 degrees F.

While they can expand they are not the first choice for high-temperature primary bricks. They are, however, much better suited to back up bricks. The higher the content of the alumina the better off the bricks are for industrial uses. They are also sometimes made of alumina and chrome which makes them perfect for industrial uses that will expose the bricks to both hot and cold temperatures. They can also be resistant to acidic slags.

The alumina in the bricks allows them to have good load bearing capabilities. Again, this is what makes them hold up in even the toughest conditions in industrial uses. For them to be considered high alumina they have to be made mostly of lower alumina silicates or clay.

These bricks have excellent load resistance in industrial uses when they contain some mullite crystals. They can be purchased online from quality manufacturers.

Understanding Classifications And Uses Of Alumina Refractory Bricks

While it may seem that you can use any refractory brick and be fine, the truth is much different. Sadly, different bricks are suitable for different projects, and using the wrong one may cost you money, cause accidents, or simply cause you to not generate as much heat. When you are working with something that requires a large amount of fuel, this can make or break your operation. Many companies fail each and every year because they don’t do their research and assume that the materials they have picked out will do the right job.

Looking up the different classifications and uses of the alumina refractory bricks you want to buy, or any bricks that you are planning to use, is a simple step that could save you thousands. This information is usually readily available from the manufacturer and will give you a better chance at making an informed decision. If you cannot find the information on the manufacturers website, you should contact them and discuss the project that you are planning to undertake. They should be able to tell you what is recommended and may even be able to help you figure out how much you need to buy.

If you still don’t understand what you need to use, there are also online communities available that can help you make the right decision. Find a community that revolves around the industry you are looking to outfit yourself with bricks for and ask what they use and why. Most of the time they will be more than happy to answer as people who fail within the industry and don’t deliver on the things that they promise, actually make them look bad as well.

Good luck figuring out the proper classifications and uses of the alumina refractory bricks for your personal or business projects.
