High Temperature Thermal Physical Measurement Instruments

ITL scientists have developed several major system that are now offered to the technical communities worldwide. The design and reliability of the systems stem from the solid experience and high professional standards of ITL scientists who developed them.

Among the main advantages of our systems one can mention the possibility of measuring together with the apparent thermal conductivity and diffusivity properties their radiative and true conductive components. These parameters become important for a large class of materials semitransparent to IR radiation (glasses, highly porous insulation, dense ceramics, etc.) when application of ASTM Standards is limited or forbidden.

The temperature range of measurements offered by our systems (up to 1800 °C) is also unique for rough refractories and highly porous insulation materials.

Advantages of ITL instruments:

• The measurement of both apparent and the true (conductive) components of thermal conductivity/diffusivity can be carried out.
• Optical properties required for thermophysical measurements and RCHT calculations are measured.
• Unique temperature range for rough disperse refractory and insulation materials: -100 up to1800 °C that allows for high temperature measurements for rough disperse anisotropic materials.
• Possibility of measurements of apparent properties during physical and chemical transformation in materials: sintering, drying, phase changes, chemical reactions, sublimation, etc.
• Measurement time of thermal diffusivity is 5-10 times shorter than for steady state and transient hot wire methods.
