Wood-ceramics Prepared form Liquefaction Wood and Wood Powder

摘要

A wood-ceramics makes from liquefaction wood and wood powder, the basic property connects with sintering temperature and liquefaction wood content. Thermo gravimetric analysis indicates that higher liquefaction wood content lead to reduce the weight loss. Scanning electron microscopy observation shows that wood powder is as a natural plant template and the basic structure of wood can partly keep. The apparent density increases before about 1100°C, and then decreases as temperature gets further; but the apparent porosity increases continuous; bending strength increases from 8.45 MPa to 11.87 MPa when the liquefaction wood content raises 60%-120%. Meanwhile, elevation of liquefaction wood content and sintering temperature can reduce abrasion loss.
