Abstract: Split bricks were prepared using purple stone and ceramic clay as main raw materials and molybdenum slag as an admixture. The water absorption, bending strength, saturation coefficient, and thermal stability were measured. The main phase structure was characterized by X-ray diffraction (XRD). The result showed that the split bricks sintered at 1080 °C could have the maximal amount of molybdenum slag admixture of up to 30 percent, the waster absorption of 5.03 percent, the bending strength of 18.54 MPa, and the freeze-thaw resistance and thermal stability up to the industrial requirements.

Key words: split brick; purple stone; molybdenum slag
