Abstract
A process for producing a cadmium free electrical contact material having at least one metal and magnesium stannate Mg2SnO4. The process includes mixing pulverulent magnesium stannate Mg2SnO4 or a mamesium stannate precursor compound with at least one metal powder and optionally further oxides, pressing the mixture in order to obtain a compact and sintering the compact to obtain a sintered body.

A process for producing a cadmium free electrical contact material comprising at least one metal and magnesium stannate Mg2SnO4, said process comprising mixing pulverulent magnesium stannate Mg2SnO4 or a magnesium stannate precursor compound with at least one metal powder and optionally further oxides, pressing the mixture in order to obtain a compact and sintering the compact to obtain a sintered body.
A method of producing an electrical contact part, comprising:
- producing a cadmium free electrical contact material, comprising at least one metal and magnesium stannate Mg2SnO4, by mixing pulverulent magnesium stannate Mg2SnO4 or a magnesium stannate precursor compound with at least one metal powder and optionally further oxides, pressing the mixture in order to obtain a compact, and sintering the compact to obtain a sintered body;
- and
- reforming the sintered body to form an electrical contact part.
A method of producing a moving switch part of a switch device or electrical switch device, comprising:
- producing a cadmium free electrical contact material, comprising at least one metal and magnesium stannate Mg2SnO4, by mixing pulverulent magnesium stannate Mg2SnO4 or a magnesium stannate precursor compound with at least one metal powder and optionally further oxides, pressing the mixture in order to obtain a compact, and sintering the compact to obtain a sintered body;
- and
- reforming the sintered body to form a moving switch part.
