Woodceramics which was prepared from pine wood powder and liquefied wood as principal raw materials were activated with KOH as activator, and the low-temperature nitrogen adsorption method and scanning electron microscope(SEM) were employed to survey and observe the effects of activating temperature on the pore structure. The results show that the activating treatment can greatly increase the mesopore and micropore. Its pore structure is a typical H3 type, and most pore diameter distributes in 1.7~2.6 nm, and it still keeps the native pore stru...
