General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.
Zinc antimonide (Zn4Sb3) is a p-type high-performance thermoelectric (TE) material, which is of interest because of its low cost, relatively large abundance, low toxicity, and low thermal conductivity. It can be used as an anode for lithium-ion batteries.

Application

Zn4Sb3 is one of the most efficient thermoelectric material mainly due to its extraordinarily low thermal conductivity in conjunction with the electronic structure of a heavily doped semiconductor. It can be doped with different elements like Pb, Sb etc to further enhance its thermopower.

beta-Zn4Sb3 is an outstanding thermoelectric material mainly due to its extraordinarily low thermal conductivity, which is similar to that of glasses. Recently it was proposed that interstitial Zn atoms are responsible for this peculiar behavior. Here we report on the

By converting waste heat into electricity, thermoelectric generators could be an important part of the solution to today's energy challenges. The compound Zn(4)Sb(3) is one of the most efficient thermoelectric materials known. Its high efficiency results from an extraordinarily low
