Researchers Discover A New Inorganic Material With Lowest Thermal Conductivity Ever Reported by University of Liverpool

This new material, with two combined arrangements, has a much lower thermal conductivity than either of the parent materials with just one arrangement. This unexpected result shows the synergic effect of the chemical control of atomic locations in the structure, and is the reason why the properties of the whole structure are superior to those of the two individual parts. If we take the thermal conductivity of steel as 1, then a titanium bar is 0.1, water and a construction brick is 0.01, the new material is 0.001 and air is 0.0005. Approximately 70 percent of all the energy generated in the world is wasted as heat. Low thermal conductivity materials are essential to reduce and harness this waste. The development of new and more efficient thermoelectric materials, which can convert heat into electricity, is considered a key source of clean energy. Professor Matt Rosseinsky said: “The material we have discovered has the lowest thermal conductivity of any inorganic solid and is nearly as poor a conductor of heat as air itself.”
