Abstract

The optical properties of the intermetallic compound PtAl2 were altered by the addition of 5% –25% copper by mass. It was found that these additions cause the colour of the compound to change from the brass-yellow of PtAl2 through orange to copper-pink. The colour of the intermetallic compounds has been described using the CIELab and chromaticity colour-measuring systems. The effect of the copper additions on the lattice parameter and band structure is discussed, related to the associated change in colour of the intermetallic compound. The effect of the copper additions on the physical and mechanical properties of the material has been studied.
