The large amounts of accumulated titanium (Ti)-bearing blast furnace slag are not only an industrial waste but also an important Ti resource. TiSi 2 is widely used in high-tech industries and is normally prepared using high-purity Ti and Si as the raw materials. In this study, a new approach, Si–Ti solvent refining, has been proposed to prepare high-purity …
The slag can form powder after grinding. When the specific surface area of slag powder is more than 400 m 2 /kg, the strength of the cement is obviously enhanced [1]. So how to ensure the quality and yield of slag powder has been an important issue. Slag powder is a multivariate, strongly coupled and nonlinear process.
