Zone-Melted Ingots

Thermoelectric materials manufactured using this technique cannot compete with polycrystal extruded materials in terms of mechanical strength. Nonetheless, zone-melted materials can be useful in power generating applications because the diffusion of component-commutating materials is obstructed within the melted structure when compared with polycrystal structure which reduces the degradation rate of a conductor.

Another advantage of zone-melted materials is their rather lower production cost.

RusTec manufactures Bi2Te3-Sb2Te3 and Bi2Te3-Bi2Se3 ingots of 20-30 mm in diameter.

Standard specification:

Length: 120 mm

Conductivity: 850-1150 Ohm-1 cm-1 (other conductivity range is available on request)

- RoHS compliant
