Knowledge is of only limited value to society unless it is accessible to all those who can understand and make use of it; indeed it was to make information on the fundamental properties and industrial applications of the platinum group metals more readily available that Platinum Metals Review was founded by Johnson Matthey in 1957. Since that time many studies of these metals have been made but, unfortunately, much of the established data still remains widely, and inconveniently, dispersed throughout the literature.
To overcome this difficulty in a particularly important area of materials science a group of colleagues under the guidance of Professor Tan Qinglin, Director of the Institute of Precious Metals, at Kunming in the People’s Republic of China, has collected together the phase diagrams of all alloy systems containing the so-called precious metals published up to the end of 1975. Over 500 systems are presented in this book, including 199 binary, 115 ternary and five quarternary systems that contain a platinum group metal.
In view of the rate of progress in this aspect of physical metallurgy none of the diagrams has been evaluated or reviewed; despite this the publication is a most useful addition to the literature on the platinum group metals. Although nominally in Chinese, English translations are given wherever this is required.
The contents pages list systems in alphabetical order according to the chemical symbols of the component elements. Interestingly, the compilation has enabled gaps in the knowledge to be identified; even among binary systems phase diagrams of rhodium, iridium, osmium and ruthenium are still rather scarce.
