High Pressure Thermal Conductivity

Why would you need high pressure thermal conductivity?

Measuring a material’s property at specific conditions which it may be used at will shed insight into how it will behave and perform. By measuring the thermal properties of a given material a high pressure, this may shed insight into how it’s thermal properties behave at elevated pressures and temperatures. C-Therm Technologies High Pressure Liquids and Solids cells both are unique capabilities, solely available at TAL, allows for the measurement of solids, liquids and powders at elevated temperatures and pressures. At high pressures, a solid sample will compress, liquids will remain condensed and powder beds will become more compact, and this will affect the thermal conductivity of the given material.

What applications would high pressure thermal conductivity measurements be beneficial for?

Applications for high pressure conductivity range from petrochemical to polymer samples. For the high pressure liquids and powders cells, we offer thermal conductivity and effusivity measurements from ambient to 300 °C with pressures as high as 1000 psi (69 bar, 6.8 MPa). This may be used to study how coolant liquids perform under pressure, how crude oil behaves under pressure, or for measuring flammable liquids at high temperature and pressure. As for the solid’s cell, we offer high pressure solids testing services from ambient temperatures up to 200 °C, with pressures ranging from ambient to 2000 psi (137 Bar, 13.7 MPa). This is perfect for measuring solid polymer samples, porous ceramics, crystalline solids and core samples for geology and fracking.

Applications space

There is a wide range of applications which high pressure conductivity measurements may be applicable for, including:

High pressure liquids cell

  • Petrochemical liquids
  • Additive manufacturing powders
  • Liquid Polymers and pre-polymers
  • Chemical reactions
  • Flammable liquids

High pressure solids cell

  • Petrochemical core samples
  • Geological samples
  • Polymers
  • Meso-porous and porous ceramics
