Si and [Al.sub.2][O.sub.3] powders by (a) measuring the composite compacts made from binary mixtures of Si and [Al.sub.2][O.sub.3] with PMMA, and (b) calculating [epsilon]' and [epsilon]" of Si and [Al.sub.2][O.sub.3] powders from (1) with n = 2.
The values of [epsilon]' and [epsilon]" of silicon and alumina powders were calculated for values of [alpha] in the range from 0.3 to 0.6 and then used in (1) (also for 0.3 [less than or equal to] [alpha] [less than or equal to] 0.6) for computing complex permittivity of four composite compacts produced by adding both silicon powder (in volume fractions from 0.0574 to 0.1312) and alumina powder (in volume fractions from 0.0575 to 0.1388) to the PMMA environment.
However, the quantity and content of published works in this area do not seem sufficient to draw a plausible conclusion about successfully preparing Mo-Cu powders with good sinterability and Mo-Cu composite compacts with excellent performance.
