    Thermal conductivity of B2O3 glass under pressure (1985)
    Springer
    International journal of thermophysics 6 (1985), S. 267-273 
    Details
    ISSN: 1572-9567
    Keywords: high pressure ; thermal conductivity ; vitreous boron trioxide
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The thermal conductivity, λ, of vitreous boron trioxide was measured, using a hot-wire procedure, from 170 to 570 K and under pressures of up to 1.7 GPa. The thermal conductivity at room temperature and zero pressure was found to be 0.52 W · m−1 · K−1. The values of the logarithmic pressure derivative, g = d(ln λ)/d(ln ρ), where ρ is the density, were found to be 1.1 for uncompacted glass and 0.7 for glass compacted to 1.2 GPa. The variation of λ with temperature at constant density was approximately linear, with a positive slope of 1.38×10−3W·m−1·K−2.

    Thermal Diffusivity of Semitransparent Materials Determined by the Laser-Flash Method Applying a New Analytical Model (1998)
    Springer
    International journal of thermophysics 19 (1998), S. 941-949 
    Details
    ISSN: 1572-9567
    Keywords: analytical model ; glass ; laser-flash method ; radiative heat transfer ; thermal conductivity ; thermal diffusivity
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract We have developed an analytical model to determine the thermal diffusivity of nonscattering materials from samples with low optical thickness and opaque boundaries with arbitrary emissivities. The paper outlines the new analytical model and describes measurements on two samples: a microscope slide glass and a high-grade fused quartz plate. Results show that the new model applied to measurements on gold- or graphite-coated samples leads to the same results as if a conventional model is used on gold-coated samples.
