The science and technology of slags for iron and steelmaking

In the quest to generate information pertaining to the characterization, pr operties and performance of molten slags, measurements and models are two i nterdependent requirements. Without measurements, our models are incomplete and unsatisfactory. Without models, we fail to realize, or perhaps even co mprehend, the potential significance of our measurements. In this context, the concept of optical basicity will be revisited and examples presented of how optical basicity can be used to design slags with appropriate characte ristics for specific applications in iron and steelmaking.
