Data on Thermal Conductivity of Thermal Insulation Boards
The CSV file contains the data on the relationship between thermal conductivity of the fibrous fumed silica compacts and temperature in Fig. 5 of the manuscript. The specimens are (1) hydrophilic silica added, (2) hydrophobic silica added, and (3) after 400 ℃ heat treatment of the board (2).
Thermal conductivity (λ) is calculated using the following equation.
λ = αcρ (α: thermal diffusivity, c: specific heat, ρ: density)
