BCN ceramic powder was prepared from pyridine-borane complex as starting material and spark plasma sintering (SPS) of the powder was performed on the condition at 2073 K for 10 min in a vacuum (heating rate: 90 K h<SUB>-1</SUB>, pressure: 39 MPa, diameter: 10 mm). Crystallization of layered BCN ceramics was progressed by SPS. The interlayer spacings were 0.341 nm after SPS and 0.347 nm before SPS. The density was 2.43 mg m<SUB>-3</SUB> after SPS and 2.40 mg m<SUB>-3</SUB> before SPS. The hardness of Hv=65 was obtained by SPS. The electrical conductivity in the direction parallel to the pressing direction was about 100 S m<SUB>-1</SUB> and that in the direction perpendicular to the pressing direction was about 200 S m<SUB>-1</SUB> at room temperature.
