Lead Telluride is a narrow gap semiconductor that has low thermal conductivity.
The maximum figure of merit is slightly lower than that of bismuth telluride, lead
telluride extents the temperature range covered for thermoelectric applications with
comparable good efficiencies. Santech Materials can produce high purity Lead Telluride
in powder, stick and target form.
