Fire tests and thermal analyses of LSF walls insulated with silica aerogel fibreglass blanket

Study on diffusion coefficient of benzene and ethyl benzene vapours in nanoporous silica aerogel and silica aerogel-activated carbon composites

In this study, nanoporous silica aerogel and silica aerogel-activated carbon composites have been synthesized using a water glass precursor by cost effective ambient pressure drying method. Equilibrium and kinetics of benzene and ethyl benzene adsorption on silica aerogel and its composites have been measured in a batch mode at tree weights of adsorbent. For the first time, the experimental dat...

Preparation and Characterization of Silica Aerogel Microspheres

Silica aerogel microspheres based on alkali silica sol were synthesized using the emulsion method. The experimental results revealed that the silica aerogel microspheres (4-20 µm in diameter) were mesoporous solids with an average pore diameter ranging from 6 to 35 nm. The tapping densities and specific surface areas of the aerogel microspheres are in the range of 0.112-0.287 g/cm³ and 207.5-66...

Fire Tests and Analyses of a Rail Cask-Sized Calorimeter

Three large open pool fire experiments involving a calorimeter the size of a spent fuel rail cask were conducted at Sandia National Laboratories’ Lurance Canyon Burn Site. These experiments were performed to study the heat transfer between a very large fire and a large cask-like object. In all of the tests, the calorimeter was located above the center of a 7.93m diameter fuel pan, elevated 1m a...

Comparison between flexural and uniaxial compression tests to measure the elastic modulus of silica aerogel

Sche The Young’s moduli of a set of silica aerogels have been measured by two techniques: 3-point bending and uniaxial compression. The data found by the two methods differ strongly. The uniaxial compression test g...
