Physical and chemical indicators of magnesia carbon brick

Magnesia carbon brick is a type of refractory brick that is made from high-purity magnesia and graphite. It has excellent corrosion resistance, thermal shock resistance, and high-temperature performance, making it widely used in steel-making applications.
Here are some common physical and chemical indicators of magnesia carbon brick:
1.Physical Indicators:
Bulk density: 2.9-3.2 g/cm³
Apparent porosity: 2-10%
Crushing strength: ≥50 MPa
Thermal conductivity: 12-15 W/(m·K)

2、Chemical Indicators:
MgO content: ≥85%
Carbon content: 8-20%
Impurity content (SiO₂, CaO, Fe₂O₃): ≤2%
Thermal expansion coefficient: 0.5-1.5×10⁻⁶/°C
Refractoriness: ≥2000°C
It's important to note that the specific physical and chemical indicators of magnesia carbon brick can vary depending on factors such as the quality and purity of the raw materials, the manufacturing process, and the specific application requirements. As such, it's recommended to consult with a qualified engineer or supplier for guidance on selecting, installing, and maintaining magnesia carbon brick for a particular application.
