Abstract
Beta-SiC powder was synthesized by carbothermal reduction of silica co ntained in rice hull ash, and porous ceramics were fabricated by conve ntional sintering. Electrical conductivity and Seebeck coefficient wer e measured as functions of temperature under Ar atmosphere to evaluate their applicability to thermoelectric energy conversion. Thermoelectr ic properties of beta-SiC ceramics fabricated from rice hull ash were comparable to those fabricated from a commercial high-purity powder.
