Abstract
A sintered electric resistance body consists of MoSi2 (with or without 0.1-5.0% Al and minor amounts of Al2O3, Zr2O3, BeO or SiO2 and has end portions which contain 0.1-20% of an oxide which melts below 1400 DEG C.; which has been solidified from a melt and which covers the silicide particles at the body and pore surfaces. The oxide may be uniformly distributed throughout the end portions or there may be a concentration gradient with the greater proportion of oxide in the cooler outer end of the endpiece.ALSO:A sintered electric resistance body consisting of MoSi2 has end portions containing 0.1-20% of an oxide which melts below 1400 DEG C., which has been solidified from a melt and covers the silicide particles at the surface and the pore surfaces. The MoSi2 of the central section may have an addition of an oxide melting at above 1400 DEG C. (e.g. Zr2O3, Al2O3, BeO or SiO2) and also 0.1-5% of aluminium. The oxide component in the end portions may be uniformly distributed there-throughout or there may be a concentration gradient with the greater proportion of oxide in the cooler outer end of the end piece. The separate parts may be sintered separately and then joined by junction discs of MoSi2 which may be of a larger diameter than the rest of the body. 0.01-1.0% of an iron group metal (Fe, Co or Ni) may be added to the composition as a sintering aid. In examples the powder mixture is homogenized, mixed with a plastifying and bonding agent, extruded in a vacuum extrusion press and sintered in reducing and oxidizing atmospheres.
