Thermal Insulating

This study describes the manufacturing process of thermal insulating composites which made from fumed silica powder, reinforcing fibre and other additives using advanced mechanofusion technique. The research focuses on the effect and mechanism of Al2O3powder on thermal insulating composites, which using as high temperature shrinkage inhibitors to restrain sintering in fumed silica compacts at high temperatures. The results show that nanosize Al2O3powder can effectively improve the volume stability of the compacts above 800°C, but which has little influence on thermal conductivity at higher temperatures. The compacts prepared in this study exhibit fracture strength of 0.26 MPa at room temperature, thermal conductivity of 0.0336 W/(m•K) at 1000°C and tiny volume shrinkage about 1.1% at 1000°C for 12h.

The Impact

SiO2 is a good performance of high temperature wave-transparent materials, but the impact of the material properties of the components of the wave through it there are some drawbacks. This study intended to determine the theoretical dielectric properties of this material. Based on Debye theory, describes the dielectric properties of the composite material at high temperature multi-scale model, discuss the impact of factors on the micro and mesoscopic dielectric properties.
