The effect of dopants during the stage of reduction, sintering, swaging and drawing has been investigated. Another investigation has been carried out to examine the effect of dope pore (bubble) dispersion on the formation of non-sag structure and on the high temperature tensile strength in tungsten wires. Additional Al to K and Si as dopant effectively increases K included in tungsten metal particles and therefore, results in increasing the contents of K in wires. Consequently, this factor contributes to the formation of numerous bubble rows and of large elongated recrystallized grains, and induces the high temperature tensile strength in wires. Improvement of bubble row dispersion is very important to get good quality of tungsten wires.
