Research in the Field of Composite Materials Based on HCBS and Refractory Materials Based on the System Al2O3–SiO2–SiC. Part 2

Abstract

The effect of heat treatment duration of the properties of specimens prepared on the basis of composite composition HCBS in the Al₂O₃–SiO₂–SiC system is studied. With a content of 10 and 30% SiC in specimens its fineness varies within the limits 3 – 200 μm. Amethod is proposed for evaluating the degree of SiC oxidation within composite material. Depending on specimen composition this index is within the limit 50 – 100%. Maximum values of σ_ben and σ_co for SiC-containing specimens reach 80 and 390 MPa respectively.
