Xh. Cui et al., Studies on the phase transformation and stability of the sintered compactsFeSi2 doped with Mn and Co, CHEM J CH U, 20(12), 1999, pp. 1954-1956
In this paper , p-type Fe1-xMnxSi2 (x = 0-0.12) and n-type Fe1-yCoySi2 (y =
0-0.12) were synthesized by means of ceramic technology. The influence of
additive amounts of Mn and Co, and heat treatment on the amounts of beta-ph
ase formed were studied. Experimental results indicate that addition of Mn
and Co could inhibit the amounts and velocity of phase formation. High rela
tive density(D-r) of p-type Fe1-xMnxSi2 and n-type Fe1-yCoySi2 causes excel
lent corrosion resistance and heat-resistance which are beneficial for manu
facture of thermoelectric components.
