METHOD FOR PRODUCING POROUS CASTINGS Russian patent published in 2017 - IPC B22D25/00 

Abstract RU 2637442 C1

FIELD: metallurgy.

SUBSTANCE: crushed sylvanite and/or wastes of its production and/or wastes of production of potassium fertilizers on its base are used as a pore agent to form an insert heated to the temperature of 500°C and placed in a mould cavity. Melt of metal or alloy which melting point is lower than or equal to 680°C is poured into the mould. The pore agent is impregnated by the melt due to the static pressure and two-sided compression in the casting mould by squeezing.

EFFECT: production of integral and partially porous castings of complex configuration, different size groups with the variation position of the all-metal part.
