What is firebrick?
Refractory facing brick is a type of brick that is produced from refractory clay that is abundantly found in the country's mines and has a very high quality. As mentioned above, the molecular structure of firebricks is dense and delicate, that's why firebricks are used for decorative purposes and building appearance. The basic materials are refractory bricks, very special minerals and refractory mineral pumice.
What are the ingredients of refractory bricks?
These materials have a very high temperature resistance, that's why the bricks produced from these materials are called refractory bricks. It should be noted that the raw materials for the production of refractory bricks are also called refractory materials. Refractory materials are non-metallic materials that have very high thermal resistance and can maintain their stability at very high temperatures. Refractory materials must be able to maintain the desired physical and chemical properties at high temperatures.< /p>
How to produce firebrick?
In order to produce refractory bricks, it is necessary to first grind ores and raw minerals and turn them into soft soil. Then these materials are placed in special ovens at a temperature higher than 1500 degrees Celsius for 3 days to bake the bricks. The product taken out of the furnace is called refractory brick.
Introduction of firebricks
Review of red firebrick
Red firebrick, also known as Semiram brick or English brick, includes dark to light shades of red. Refractory English brick can be produced and supplied in orange, mustard, yellow, crimson, liver, black and red colors.
Introduction of white and gray refractory bricks
White refractory brick and gray refractory brick are used for decoration and the interior of the building. Using white and gray refractory bricks due to their special color, you can give a beautiful appearance to the decoration and interior of the building.
Black and brown refractory brick
Black and brown refractory bricks require a higher heat degree than other refractory bricks. Combining black and brown refractory brick with stone and composite, you can create a very attractive look. It should be noted that due to the greater difficulty of producing black and brown refractory bricks, the price of this type of refractory brick is higher than other refractory bricks.
Orange and mustard refractory brick
Among other types of refractory bricks, we can mention its color range from orange to cream and gold, which is also known as chamouti refractory bricks. The price of Chamoti firebrick is slightly higher than English firebrick.
Types of refractory bricks based on application
The wide variety of firebrick has made it possible to use it in a wide range of building facades. Among the uses of firebrick, we can mention the construction of barbecues, fireplaces, furnaces and ovens, construction of sheds, flooring and interior decoration of buildings.
Barbecue fire brick
Barbecue firebricks are used both in the construction and in the facade of barbecues. The most common dimensions of firebricks for building barbecues are 5.5x10x20 and the most common dimensions of firebricks for barbecues are 2.5x7. It is at 32. Of course, 2.5 x 5.5 x 26 cm bricks are also used a lot in barbecue facades. Barbecue firebrick is one of the most popular materials for making barbecue, because it has a good price while being beautiful and strong.
Fire bricks for fireplaces, furnaces and ovens
One of the distinctive features of the refractory brick is its high temperature resistance, which makes it possible to use it in the construction of fireplaces, furnaces, and ovens. The refractory brick of the fireplace is more of the brown and black type, which has a higher temperature resistance than the rest of the facade bricks.
Implementation of the exterior of the building using fireproof bricks
Refractory facing bricks are highly popular due to their stability against adverse weather conditions such as sudden changes in day and night temperatures, destructive acid rains, erosion, and long life span. Another reason for the popularity of refractory brick is its lower price compared to other building materials used in building facades. It should be noted that due to the great variety of these materials, it is possible to implement all kinds of building facades in different designs and colors.
Using refractory bricks for flooring
The effectiveness of refractory brick is not only limited to the interior and exterior of the building and the construction of fireplaces and barbecues, but this widely used product is used in flooring such as garden flooring, carpet flooring in areas, yards, and sidewalks.

Fire brick does not rust
The presence of silica, aluminum oxide and iron in the composition of refractory bricks has caused the salt in these bricks to be zero and they do not cause dandruff. The dandruff that is observed after the installation of firebrick is due to the mortar and water that is applied behind the brick. The best way to prevent the refractory brick from scaling is to use nano brick. In this way, approximately one to two weeks after the implementation of the refractory brick facade and its drying, nano bricks are applied to the surface of the brick so that water permeability becomes zero.
Review of special refractory bricks
The level of resistance of special brick to heat is higher than other refractory bricks. This brick is generally stronger than other bricks. The difference between special firebrick and other firebricks is that transition metals are used in the construction of this type of brick in combination with raw materials, which has created special properties in it.
