(57) The invention relates to clinker particles which can be used as a Cr(VI) reducing agent in production of cement. The clinker particles have a particle core of the clinker material comprising at least calcium silicates, calcium aluminates and iron compounds. The particle core is at least partially coated with a surface layer comprising iron-rich material, preferably in form of ferrites. The invention relates also to a method of making clinker particles. In the method, iron-rich material is applied on the clinker particles after the sintering zone but before clinker particles are cooled down to a temperature of <900 °C.
