What material is used as refractory material

Any substance that has an extraordinarily high melting point and retains its structural performance at extremely high temperatures is said to be Refractory. Refractory bed material suppliers made this with ceramics and are widely used in the metalworking, briquetting, and ceramics sectors. These materials are shaped into a variety of forms and lined within furnaces, ovens, and other equipment that processes materials at high temperatures.

Numerous ceramics have particularly good mixtures of high melting points and chemical stability, which makes them valuable as refractories. This is because of the significant strengths displayed by their fundamental chemical bonds which have been highly used in different sectors.

In the blog, we’ll look at the many sorts of refractory materials used in factories 

Fired Refractory Products

Fired refractory goods are refractory materials made from gritty and powdered refractory natural resources and polymers by churning, molding, curing, and elevated fire. It is one of the most often used types of refractory brick because refractories manufacturers and refractory bricks suppliers believe it to be extremely affordable and to have easily available raw materials. 

Fireclay refractories

Hydrated aluminum silicates with 25%–45% Al2O3 and 50%–80% SiO2 and trace amounts of other minerals make up the majority of fireclay refractories. Fireclay tile is the most popular form of refractory brick and is used extensively in most burners, ovens, heaters, thermoelectrics, etc. 

Silica brick

A refractory substance called silica brick contains at least 93% SiO2. High-quality rocks make up the raw material. At temperatures close to its real fusing point, silica brick possesses enhanced mechanical toughness.



Clay Bricks

With an AL203 concentration of 30% to 48%, clay bricks are an alumino – silicate refractory material made of magnetite, glass stage, and cristobalite. They are frequently used in masonry blast furnaces. 

Magnesite refractories

Materials that contain at least 85% of overall magnesium oxide are known as “magnesite refractories.” These are produced using Silica and naturally occurring magnesite (MgCO3) (SiO2). The physical characteristics of this type of bricks are often subpar, and their main strength lies in their resistance to basic slags, especially those that are iron and lime enriched. 

Chromite refractories

In contrast to magnesite-chromite refractories, which typically have at least 60% MgO and 8– 18% Cr2O3, chrome-magnesite materials often have 15–35% Cr2O3 and 42–50% MgO. The critical routes of high-temperature furnaces are constructed using chrome-magnesite refractories. These substances can tolerate fumes and acidic sludges. 

Zirconia refractories

The strength of zirconia refractories is extremely strong at ambient temperature and is retained up to a temperature of 15000C. It fails to interact strongly with fluid metals and melted glassware because its thermal conductivity is substantially lower compared to the majority of many other refractories. 

Insulating materials

To cut down on energy loss, insulating materials like high porosity refractories with low thermal conductivity. Comparing insulating materials to firebricks, the former has a lesser density while the latter gives a better level of heat resistance.

Conclusion Refractory material serves as a fundamental building block for the development of technology as well as manufacturing and operation in the industrial sectors.
