Abstract
powder (1‒2 micron) in the ratio of 1:2 were used. The test-beams of the size 60×15×5,5 mm were obtained by means of uniaxial semi-dry compacting under the pressure of 50 MPa (for mono-fractional compositions) and of 25 MPa (for three-fractional compositions). The samples were burnt on the air at the temperatures from 1350 to 1550 °C. The open porosity varied from 28 to 43 %, the ultimate bending strength varied from 1 to 36 MPa. The highest strength was attained when the SiC‒MgO binder was used (5 wt. % of the binder over 100 % of the aggregate, the ultimate bending strength was 36 MPa, the open porosity was 30 %). Ref. 12. Tab. 5.
