A method of extruding an electrode, batch material, particularly a zinc or nickel, electrode material, and an extruder assembly for extruding the material, are described. The method and extruder are designed to produce a low compaction of the material and low, back pressure, whereby working of the batch material is limited.

Extruding electrode material

This invention is directed to the preparation of alloy articles consisting essentially of 65 wt. % or more glass and high temperature organic thermoplastic or thermosetting polymers having working temperatures which are compatible with that of the glass and/or the precursor glass for the glass-ceramic. The glass and polymer are combined at the working temperature to form an intimate mixture; i.e., the glass and polymer are in a sufficiently fluid state to be blended together to yield a body exhibiting an essentially uniform, fine-grained microstructure wherein, desirably, there is at least partial miscibility and/or a reaction between the glass and the polymer to promote adhesion and bonding therebetween. A body is shaped from the mixture and cooled to room temperature.

A body is shaped from the mixture and cooled to room temperature.

The instant invention discloses a method for forming glass/polymer alloy or composite pellets of a uniform shape, and exhibiting an increased density and pellet integrity/strength. The pellets are formed by melt-blending and extruding a semi-molten strand of the glass/polymer alloy or composite and subsequently compressing and cutting the strand into pellets at a predetermined pelletizing temperature. The predetermined pelletizing temperature is that temperature at which the glass/polymer alloy or composite extruded strand is still semi-molten and deformable and at which the so-formed pellets will maintain the shape imparted to them.
