Ambient pressure dried shape-controllable sodium silicate based composite silica aerogel monoliths

The preparation process of silica aerogels has commonly involved a dangerous supercritical drying step, so work has been done to eliminate this step. This paper discusses the preparation of composite silica aerogels containing silica fibers using a method that excludes the supercritical drying step. The ...

Tailoring the structure of cellular vitreous carbon foams

The authors set out to prepare cellular vitreous carbon (CVC) foams with varying thermal and physical properties. This was accomplished by using tannin-based resin modified by different isocyanates in varying amounts. Three different experimental procedures were used to prepare foams with different physical and thermal ...

Porous mullite ceramics with low thermal conductivity prepared by foaming and starch consolidation

Using industrial grade mullite powder and a foaming and starch consolidation process, a series of porous mullite ceramics were prepared. These ceramics were analyzed by a thermal constants analyzer, and it was determined that the ceramics had low thermal conductivities and would make good thermal ...

Temperature dependence of effective thermal conductivity and thermal diffusivity of treated and untreated polymer composites

The thermal properties of a series of treated and untreated oil palm fiber-reinforced composites were tested at room temperature and atmospheric pressure using the TPS method. Treatment of the composites with varying methods resulted in increases in thermal conductivity, porosity and pore sizes depending on ...

Microstructure and Thermal Conductivity of Hydrated Calcium Silicate Board Materials

Two calcium silicate boards of different densities, porosities and pore size were analyzed for their thermal properties, specifically thermal conductivity. The boards were heated from room temperature to 400°C and the thermal conductivity was monitored during this time. A separate experiment 'aged' the boards first ...
