The dimension of the fineness index K f coincides with that of specific surface S sp, i.e., m –1, and this specifies material state of comminution, i.e., a value inverse to particle size.With an increase in fineness there is an increase in the role of surface phenomena during sintering. It is seen from calculated results for fineness index of …

Summary. Hematite is a naturally occurring ore of iron, the most common ore of iron and the most used source of iron. It is often sold as red iron oxide. Red iron oxide has many uses from pigments and dyes through to ceramics. Its resistance to heat and antipruritic properties mean that it is often used for casings and coverings.
