Preparation of high-porous SiC ceramics from polymeric composites based on diatomite powder

Preparation of high-porous SiC ceramics from polymeric composites based on diatomite powder

High-porous SiC ceramics (density 0.50–0.58 g/cm 3 , porosity 82–84 %, compressive stress at break 3.7–6.3 MPa) was prepared by means of polymeric technology and natural raw material (diatomite powder, “Biosilica” grade) at the temperature of carbothermal synthesis (1400 °C). It was shown that the m...

Zusammenfassung:High-porous SiC ceramics (density 0.50–0.58 g/cm 3 , porosity 82–84 %, compressive stress at break 3.7–6.3 MPa) was prepared by means of polymeric technology and natural raw material (diatomite powder, “Biosilica” grade) at the temperature of carbothermal synthesis (1400 °C). It was shown that the main phase was silicon carbide with a small (
