Abstract:
“Green”, ceramic tapes intended as building blocks for making complex, fully ceramic components and devices for electronic-, lab-on-chip-, and sensing applications, the manufacture of which comprises in sequence: I. mixing of a ceramic “green” paste, II. homogenisation of a ceramic “green” paste, III. dimensioning and optionally structuring the ceramic “green” paste, IV. drying of the dimensioned and structured ceramic paste, in which: step iii) is performed in a combination of an extruder and a calender, the extruder being provided with a circular extrusion die, splitting and unfolding the extruded tube to a flat, continuous tape strip, using methylcellulose or derivatives thereof as binder, and, an additional step chosen among cutting and punching the thus dimensioned and optionally structured “green” paste, thereby making thick, “green” tapes. A method for its manufacture is also contemplated.
