Five operational magnesia carbon bricks for refractory materials

1. Plasticity of refractory materials

Plasticity refers to the performance of refractory materials mixed with binders and diluents to a specified consistency and kneaded into shape. When subjected to external forces, although the shape changes, it does not crack. Generally speaking, all refractory materials with added binders possess plasticity. Refractory plastics, ramming materials, bonded clay, or materials mixed with certain binders have obvious plasticity properties, but the plasticity of semi dry formed products compressed by machinery.

2. Adhesion of refractory materials

Refractory brick masonry requires materials with adhesive strength at both room temperature and high temperature, so refractory slurry is usually used. Silicon based, clay based, high alumina based, and magnesium based refractory slurries achieve adhesion between refractory materials and products through intermolecular forces at room temperature. In high-temperature environments, ceramic bonding can be achieved due to sintering. In order to achieve ceramic bonding at lower temperatures, some sintering promoting agents can be added to the mud.
