In this Received 10 January 2012 study, we report a hydrothermal route for the preparation of wood powder/CaCO3 composites using the Received in revised form 9 February 2012 dewaxed wood powder. The wood powder was pretreated by the NaOH/urea solution. The urea acts Accepted 19 February 2012 2− as the CO3 source and provides a basic condition for the synthesis of CaCO3 . The influences of several Available online 25 February 2012 reaction parameters such as the heating time and the types of additives on the products were investigated by X-ray powder dif
