  • Thermal conductivity measurement method and instrument and method of producing a heat insulating material
    Patent number: 6991366
    Abstract: A method of measuring the heat conductivity of an object to be measured, comprising generating heat between the object to be measured and a heat resistant material, causing heat to flow through the interior of the object to be measured and the interior of the heat resistant material and obtaining the heat conductivity of the object to be measured from a temperature difference between at least two points of the heat resistant material, a heat conductivity measuring instrument using the same and a method of producing a heat insulating material.
