Magnesia carbon bricks are non-burning refractory materials made from high-temperature sintered magnesia or fused magnesia and carbon materials and various carbonaceous binders. Magnesia-carbon bricks maintain the advantages of carbon refractory materials and at the same time It has completely changed the inherent shortcomings of previous alkaline refractory materials such as poor spalling resistance and easy absorption of slag.
1. Custom Size Specifications

(2) Common Matching Sizes: 230×114×40/50/75/100 mm, 300×150×75 mm, 345×150×75 mm
(3) Custom Size Range: Length: 100–800mm; Width: 50–300mm; Thickness: 30–200mm
(4) Special Shapes: Wedge, arch, trapezoid, sector and other custom-shaped bricks available.
2. Custom Service Advantages
(1) Custom design based on furnace type, lining structure and working conditions.
(2) Flexible production for both small-batch trial and large-volume supply.
(3) Strict quality control with stable performance and high dimensional accuracy.
(4) Professional technical support for installation, application and lining optimization.
Features:
(1) Excellent High-temperature Resistance: Magnesia-carbon bricks can be used continuously at temperatures above 1200℃. With magnesium oxide as the main component, which has a melting point of up to 2800℃, the bricks maintain excellent stability in high-temperature environments.
(2) Strong Slag Erosion Resistance: Magnesium oxide exhibits outstanding resistance to alkaline slag corrosion, while carbon has poor wettability with molten slag. The combination of these two components enables magnesia-carbon bricks to effectively resist slag erosion and penetration, with a much thinner penetration layer compared to traditional fired basic bricks.
(3) Good Thermal Shock Resistance: Inherited from graphite’s excellent thermal shock resistance, magnesia-carbon bricks feature high thermal conductivity, low linear expansion coefficient and low elastic modulus, which prevent cracking under rapid heating and cooling conditions.
(4) High Strength at Elevated Temperatures: Magnesia-carbon bricks possess good high-temperature strength and wear resistance. They can withstand mechanical stress and abrasion under high temperatures without easily suffering structural damage or spalling.
(5) Superior Oxidation Resistance: The addition of antioxidants enables magnesia-carbon bricks to effectively resist oxidation in the air, thereby extending their service life.
