Abstract
A technology for preparing high-density (with zero open porosity) ceramics molded by casting from bauxite highly concentrated ceramic binding suspensions (HCBS) has been developed (90% Al2O3). The precursor HCBS feature a high dispersity (percentage of particles < 2 μm across in excess of 40%; median particle diameter, < 5 μm; d max = 10 – 20 μm), a high solid-phase concentration (C V ≥ 0.65), and a high fluidity. A material with zero open porosity is obtained by sintering at 1400 – 1450°C and its potential use for making grinding bodies is considered.
