Abstract
1. A filtration block for liquid alloys and metals and more particularly for aluminium, magnesium, aluminium-based alloys, and magnesium-based alloys, formed by elements, of which at least the outside part is formed by an active mineral compound, with a mechanical and a physical-chemical effect, and having an open pores structure, characterized in that said block is formed by elements sintered at a temperature which is from 5 degrees to 150 degrees C lower than the melting temperature of the active mineral compound, for a period of from 5 minutes to 1 hour, said active mineral compound being selected from alkali and alkaline-earth metal fluorides, and fluorides of magnesium and aluminium, the melting points of the sintered elements and of the active mineral compound being preferably higher than 800 degrees C and at least higher than the temperature at which the metal or alloy to be filtered is introduced onto the filtration block.
