Effect of Polymorphous Transformations of Quartz on Properties of Synthetic Moulding Sands

Jerzy St Kowalski

The study discusses the problem of the choice of moulding sand components in respect of their behaviour in contact with molten metal. Investigations of the phenomena that take place at high temperatures enable evaluation of the applicability of moulding sand composition under the actual foundry’s operating conditions, resulting in elimination of casting defects caused by moulding sand.
