摘要

Inorganic casting core sand binder for application in aluminum foundry and as a fertilizer, comprises inorganic binder containing elements and ions, preferably cations of potassium ion (K+>), calcium ion (Ca2>+>) and magnesium ion (Mg2>+>), and anions of sulfates, phosphates and oxides that can be safely used as a special fertilizer after their primary application as core sand binder.
