Abstract
A sinterable paste formulation usable as cast material in a cast-mold process, in combination with a mold material formulation, is provided. The sinterable paste formulation comprises a power of a sinterable material, in an amount of at least 85% by weight of the total weight of the formulation, a binder as described in the specification, and an aqueous solution which comprises water and a water-miscible organic solvent featuring an evaporation rate in a range of from 0.3 to 0.8 on an n-butyl acetate scale. Methods employing the formulation and objects and products obtained therefrom are also provided.
Claims22
A sinterable paste formulation usable as cast material in a cast-mold process in combination with a mold material formulation, the sinterable paste formulation comprising a powder of a sinterable material, a binder and an aqueous solution, wherein an amount of said powder is at least 85% by weight of the total weight of the formulation, and wherein said aqueous solution comprises water and a water-miscible organic solvent, wherein said organic solvent has an evaporation rate in a range of from 0.3 to 0.8 on an n-butyl acetate scale, wherein said sinterable material is a metal,
- and wherein:
- the formulation features a pH of at least 8;
- and/or
- a total amount of said aqueous solution ranges from 6 to 10% by weight of the total weight of the formulation;
- and/or
- an amount of said water-miscible organic solvent in said aqueous solution ranges from 20 to 80% by weight of the total weight of the aqueous solution.
