Magnesium Iron Spinel Brick

Magnesium Iron Spinel Bricks(also called Magnesia Hercynite Brick) are made from high - purity magnesia and ferro - aluminum spinel through high - temperature sintering. The main crystalline phases are periclase and magnesium - iron spinel phases. They are representative products of chromium - free and environmentally friendly refractory materials.

Features and Properties

1. Mechanical Properties: Formed under high pressure, they have high compressive strength and excellent resistance to thermal creep.
2. Thermal Properties: The softening temperature under load is as high as 1700 °C, and the thermal - shock resistance is stable (more than 10 cycles).
3. Chemical Properties: Resistant to the erosion of basic molten slag and have certain tolerance to acidic media.
4. Construction Advantage: They have a significant characteristic of adhering to the kiln skin, reducing the heat loss of the kiln lining.
