1. Magnesia-carbon bricks for steelmaking converters, ladles, and refining furnaces
2. Wear-resistant / friction materials
3. Magnesia-based castables and repair materials for high-temperature kilns and furnaces
4. High-end refractory materials
5. High-temperature electrical insulation fillers
1. High-temperature resistance
2. Extremely low reactivity; does not absorb water or swell upon hydration, making it resistant to cracking during storage and application
3. Resistant to erosion by alkaline slag, ensuring a long service life for the furnace lining
4. Dense and wear-resistant; withstands erosion by molten steel and clinker
5. Excellent insulation properties
