The inclusions can be divided according to their chemistry into two major categories: oxides and sulfides [4].
Complex oxide inclusions often have an amorphous structure and are referred to as silicates [3].
A final effect of inclusions on the chip formation mechanism depends not only on their chemistry but stereological parameters as well.
According to their geometry as well as chemistry they can be classified as II type sulfides.
