The friction and wear behaviors of rice husk (RH) ceramics, prepared by carbonizing the mixture of rice husk and phenol resin at $900^{circ}C$ in $N_2$ gas environment, sliding against high carbon chromium steel (JIS SUJ2), austenitic stainless steel (JIS SUS304), and $Al_2O_3$ under dry condition were investigated using a ball-on-disk tribometer. The test results show that the friction coefficient of RH ceramics takes very low values 0.05-0.08 and 0.06-0.11 sliding against SUJ2 and SUS304, respectively, and much higher values around 0.14-0.23 against $Al_2O_3$. It was also shown that SUJ2 provides the lowest specific wear rate values below $10^{-9}mm^2$/N, while, those of SUS304 and $Al_2O_3$ mostly stayed between $10^{-9}$ to $10^{-8}mm^2$/N range. The worn surfaces of counterparts were observed with optical microscopy and analyzed using cross-sectional transmission electron microscopy with energy dispersive X-ray spectroscopy and electron diffraction. It was suggested that the tribological behaviors of RH ceramics are closely related with the formation of a transferred film, consisted of amorphous silica and carbon particles, on a counterpart surface. The transferred film was formed readily on SUJ2 balls, whereas for SUS304 the presence of the film was subject of the sliding conditions. Moreover, formation of the transferred film could not be detected on $Al_2O_3$ counterparts.
