Synthesis, thermal analysis and structural characterization of the ternary compound
This paper explores the microstructural evolution of three Pb-free solders; two have a near-eutectic composition in a quaternary system, while a third has a composition along the eutectic valley of a ternary compound
. The properties and microstructures of each are compared to SAC 305.
To achieve the abovementioned wavelength, the ternary compound
semiconductor material GalnAs has been chosen.
The intermetallic on the component side is a ternary compound
, SnCuNi, with a nickel content in the range of 10-15%.
As a response to this need, a NIST scientist calculated from quantum mechanical principles the electron and hole mobilities for the ternary compound
This quarternary alloy was an improvement on a ternary compound
, [Pt.sub.65][Ru.sub.25][Os.sub.10], found by Kevin Ley, a researcher in Smotkin's group, by non-combinatorial methods.
SrO and Sr[(OH).sub.2] inclusions are unstable in aluminum melts, and form a ternary compound
that has a grain refining effect rather than one of pore nucleation.
Although some researchers have tried to increase the purity by tailoring the molar ratio of Ti-Sn-C or Ti-Sn-TiC, the almost complete conversion of the raw material to the desired ternary compound
is still a big challenge .
A much better fit is obtained by assuming the formation of a ternary compound
at the CdTe/CdS interface.
The ternary compound
known as the MAX phase ([M.sub.n+1] A [X.sub.n], where M = transition metal; A = A group element; X = C and/or N; n=1-3) and, particularly, [Ti.sub.3]Si[C.sub.2] phase, has attracted a considerable attention lately (Lopez et al., 2007; Emmerlich et al., 2004; Barosum, 2001) because of the extraordinary properties.
Only one ternary compound
was found, namely, [Ca.sub.2][AlNbO.sub.6], which is a perovskite derivative.
