Abstrakt: Bauxite-based high-density ceramic binding suspensions (HDBS) are promising materials for producing high-quality refractories. Static unilateral pressing at 200 MPa of a system composed of electrocorundum (filler) and a bauxite HDBS led to greens with a porosity of 16–17% and subsequent low-temperature firing yielded refractories with a compressive strength of about 140 MPa. The phenomenon of filler grain break-up in the course of pressing was studied. This process markedly modifies the initial grain size and weight distribution.
