Refractory brick, also known as firebrick, is a type of brick that is designed or manufactured to cope with high temperature environments. Such bricks are used in kilns and furnaces, for example. Many manufacturers around the world produce refractory bricks of different sizes, shapes and styles. Most manufacturers also offer custom-made firebricks to customers. The main advantage of using refractory brick is that it can easily withstand high temperatures without damage. Whereas other bricks get heated up so easily, this type of brick is known for its insulating nature.

Advantages of refractory bricks

Using refractory bricks or firebricks has advantages in different ways. This brick is apparently more expensive than other bricks due to its unique high-end insulation capabilities. However, in exchange for your extra investment, it offers some unique benefits that you can enjoy. Here are some of the common advantages of refractory bricks:

l Excellent thermal insulation. refractory brick is mainly due to its thermal insulation. It prevents heat from passing through it, thus making the house comfortable both in summer and winter. As the weather changes, the environment in your house won't change dramatically.

l Refractory bricks are stronger than ordinary bricks. Firebricks are stronger than ordinary clay bricks, which is why they are thought to last longer than ordinary bricks. Although the bricks are strong, they are very light in weight.

l Easy storage. In extensive or large constructional projects, it is often found that many bricks are vulnerable to damage due to improper storage and changes in climatic conditions. Use refractory brick, no storage trouble. Be sure to keep them in a dry place, as humidity can damage the bricks.

l Any shape and size. The best part with refractory bricks is that they can be customized. Most manufacturers provide buyers with custom brick sizes and measurements. So, you will get them as you wish.


Disadvantages of refractory bricks

Burned refractory bricks need to be selected and tested for rational energy to identify whether the product meets the desired shape, size, composition and performance requirements. There is no denying that refractory brick has many advantages, but it also has some disadvantages.

l Heavy weight. The weight of firebrick is relatively larger than that of other wall masonry materials, which makes the structure need to bear a larger weight and the project cost is increased.

l Poor sound insulation effect. The sound propagates into the firebrick, and the decibel of the sound decreases very little due to the small voidage and the absence of sound isolation.


Refractory brick is an essential material in industrial production. The quality of refractory brick directly affects the normal operation of the kiln. With the progress and development of high temperature industrial technology, the quality requirements of auxiliary refractories are getting higher and higher. Especially for the quality and service life of sintered refractory brick, it is widely used in the iron and steel metallurgy industry.
