Zinc-Graphite - EROS

Introduction. The reagent prepared by reduction of zinc chloride with potassium graphite does not consist of intercalated zinc; instead, very fine particles of zinc are deposited upon the graphite, which serves as an inert carrier. 1a A comparison of the conditions required to condense ethyl bromoacetate with cyclohexanone was used to demonstrate that more active zinc is formed by this method ...

Cast Irons - phase-trans.msm.cam.ac.uk

Spheroidal graphite cast iron usually has a pearlitic matrix. However, annealing causes the carbon in the pearlite to precipitate on to the existing graphite or to form further small graphite particles, leaving behind a ferritic matrix. This gives the iron even greater ductility. All samples are etched using 2% nital.
