Paulownia Wood

AbstractThe thermal conductivity properties of wood of Paulownia Clones in Vitro 112 were investigated after heat treatment at temperatures of 180 °C, 200 °C and 220 °C. After the treatment, the density decreased by 5.6, 8.9, and 14.1% for the samples heat-treated at 180 °C, 200 °C and 220 °C, respectively. The decrease in the thermal conductivity was 0, 2.6 and 15.7%, respectively. The thermal conductivity of kiri wood after thermal treatment at 220 °C was 0.064 W/mK, which is almost the same as that of thermal insulation materials.

Yttria-stabilized zirconia fibers thermal insulation materials may be the main developmental direction of high temperature thermal protection materials, due to their high temperature resistance (above 2000 °C), high strength and toughness, low thermal conductivity ( about 2 W/m·K), oxidation resistance and other excellent properties. However, mechanical property of zirconia fibers thermal insulation materials is decrease after high temperature heat treatment. In this paper, the evolution of microscopic structure of zirconia fibers is studied by using the method of oxyacethlene ablation. The gain growth and high temperature creep are observed after 600 s heat treatment at 1800 °C. Crystal phase of zirconia fibers is not changed and still cubic. Moreover, crystallinity is more higher form XRD patterns. Controlling grain growth can improve high temperature mechanical property of zirconia fibers thermal insulation materials.
