P The materials 5AlSi9Cu2 and oAlSi9Cu2 have been compared with the cooper-free two-component system 5A1SÍ12. The electron mictrobe analysis has shown that the detectrion of phases with the aid of the ecthing series of classical metallography is not quite exact ; this conctetion has been proved by examples and micrographs. K. Bakó: Mould and core coatings .......................P 8 The composition and mode of application can have positive and negative influences on the previous operations of the technological line.
