Agricultural waste of rice husk (RH) was converted into a densified carbon/silica composite with superior mechanical properties. A powder of RH produced by using a planet ball mill was carbonized and molded into the precursor, by means of binderless hot-pressing with a specialized procedure. The precursor of which bulk density was 1.36 g/cm^3 was sintered for the further densification up to 1400 ℃ without compression in nitrogen gas. The sintering at 800 ℃ provided the maximum bulk density of 1.52 g/cm^3. The maximum compressive strength and the maximum Vickers hardness at the surface were measured to be 55.7 MPa and 343 HV at the sintering temperature of 1200 ℃ and 800 ℃, respectively.
