Refractory bricks: what you need to know before buying
Refractory brick is a special type of building material that can withstand extremely high temperatures. It is widely used in the construction of stoves, fireplaces, industrial boilers and other structures subject to intense heat. Before buying this material, it is important to understand its features, characteristics and applications.

Main characteristics of refractory bricks
Resistance to high temperatures
Refractory bricks can withstand temperatures ranging from 1000°C to 1800°C, depending on their composition and type.
Composition and structure
The composition of such bricks includes clay, fireclay, corundum, magnesite and other materials that provide high heat resistance.
Density and porosity
The denser the brick, the stronger it is, but also the heavier it is. Porous versions retain heat better.
Heat resistance and resistance to thermal shock
Bricks must be able to withstand sudden temperature changes without cracking.

Types of refractory bricks
1. Fireclay is the most common type, used for stoves and fireplaces, temperature resistance up to 1400°C.
2. Quartz - tolerates high temperatures well, but is sensitive to changes.
3. Corundum - has high mechanical strength, can withstand over 1800°C.
4. Magnesite - used in the metallurgical industry.
5. Carbon - resistant to chemical attack, but used in highly specialized areas.

Where is refractory brick used?
- Home stoves and fireplaces - fireclay bricks are ideal for keeping warm.
- Barbecues and barbecues - refractory materials protect the structure from overheating.
- Industrial furnaces and boilers - used in metallurgy and ceramic production.
- Chimney systems - ensure safe operation.

How to choose the right refractory brick?
1. Pay attention to the operating temperature
Each type of brick has its own temperature limit.
2. Choose the right size and shape
There are standard (250x120x65 mm) and special shapes for complex structures.
3. Check the quality
High-quality bricks have a uniform color, no cracks or defects.
4. Check the composition of the material
Some types contain impurities that can affect durability.
