Production of a New Tin Cell at INRIM

Over the years some of the INRIM metal fixed-point cells, ≥20 years old, have shown a variable deterioration consisting in the leaking of some of the metal through the walls of the crucible. The variation in the deterioration is assumed to be connected with the frequency with which the cells have be...

Description
Summary:Over the years some of the INRIM metal fixed-point cells, ≥20 years old, have shown a variable deterioration consisting in the leaking of some of the metal through the walls of the crucible. The variation in the deterioration is assumed to be connected with the frequency with which the cells have been used. New cells are therefore being produced at INRiM as substitutes for the older cells. A description of the new cells and their preparation is given, along with a preliminary comparison between the new cell and the older cell(s).
