Synthetic magnesia dolomite sand use magnesite and dolomite as raw materials, is produced and synthesized by two-stage firing process.

　　Synthetic magnesia dolomite sand has excellent characteristics as follows:

　　1. High chemistry purity;

　　2. Excellent performance on the microstructure;

　　3. High elevated temperature strength;

　　4. Strong anti-erosion ability to converters slag;

　　5. Grate hydration resistance.

　　Synthetic magnesia dolomite sand can be used to produce ramming mass, hot repairing mass, as well as magnesia dolomite bricks for converters and ladle refining furnace, etc.
