How Much Are Magnesite Bricks?
When you consider purchasing magnesia bricks for the high-temp industry, you should want to know: How much are magnesite bricks? What is the cost of magnesite bricks? About these questions, Kerui has well-experienced sales managers to give you a free quote. Besides, it is vital for you to understand the factors that affect magnesite bricks’ price. The price of Magnesite refractory bricks can vary based on several key factors.
First – Chemical Composition
Magnesia bricks are consist of magnesium sand with fewer impurities (CaO<2.5%, SiO2<3.5%) as the main raw material. In addition, magnesite refractory bricks are alkaline refractory with magnesium oxide ( MgO) above 90%. Meanwhile, the composition of magnesite bricks may vary based on specific manufacturing processes and desired properties. However, the main composition includes the following components:
Magnesite refers to the main raw material of magnesite refractory bricks. Meanwhile, it is known for its high melting point, thermal conductivity, and resistance to high temperatures.
Various binders are added to the magnesite mixture to improve the strength of the magnesite bricks. Meanwhile, common binders include clay, magnesia cement or other refractory materials.
To improve the resistance to oxidation and extend the service life of magnesite bricks, antioxidants like chrome oxide (Cr2O3) or iron oxide (Fe2O3) can be added to the composition.
Second – Properties of Magnesite Bricks
Magnesite bricks have high refractoriness. Their refractory temperature ranges from 1500°C (2732℉) to 2000°C (3632℉). So this property makes magnesite bricks suitable for use in kilns and other heat-intensive industries.
Magnesite bricks have excellent thermal conductivity, which allows them to efficiently transfer heat within the kiln lining. For example, this property helps to keep the temperature inside the kiln stable and reduces heat loss.
The ability of magnesite bricks to handle thermal shock is critical in high-temp kilns where the refractory undergoes repeated heating. Thus, their resistance to thermal shock ensures the structural integrity and longevity of the lining.
Alkali resistance refers to the ability of the material to withstand the corrosive effects of alkalis. Besides, the composition of magnesite bricks makes them resistant to alkaline substances commonly found in industrial processes.

Fourth – Advanced Manufacturing Process
The refractory bricks manufacturing process plays an important role in the quality of refractory products. Now Kerui will introduce the magnesite bricks manufacturing process for you.
Mixing various materials composed of different particles, including raw materials, binders, other additives, and water. In addition, other additives like graphite or alumina may be incorporated to improve specific characteristics such as thermal shock resistance or corrosion resistance.
Magnesium ore is a barren material with low moisture content and generally does not deform due to air compression. With the increase of molding pressure, the strength, density, and load softening degree of magnesia bricks after firing all increase.
Dry the formed magnesite bricks to remove excess moisture. Meanwhile, this is usually done in a controlled temperature drying chamber or kiln to prevent cracking or warping. Care is taken to gradually increase the temperature during the the phase to minimize the risk of brick cracking.
The firing temperature of magnesite bricks increases with the increase of magnesium content, and the firing temperature of magnesium bricks is around 1500°C (2732℉). During this stage, the magnesite undergoes a chemical reaction, to result in the formation of a solid structure.
Once the firing process is complete, the magnesium brick blocks are slowly cooled to room temperature. Then equipment thoroughly inspected magnesium bricks to ensure quality. Meanwhile, this may include visual inspections, dimensional checks and other quality control tests.
The firebricks are carefully stacked, protected, and labeled to facilitate handling and identification. Kerui cooperates with well-known logistics companies to ensure the safe arrival of products. If there is a problem during the transportation, you can contact us at any time to solve it。
